  • Methodologies or algorithms for filling in missing data

    - by tbone
    I am dealing with datasets with missing data and need to be able to fill forward, backward, and gaps. So, for example, if I have data from Jan 1, 2000 to Dec 31, 2010, and some days are missing, when a user requests a timespan that begins before, ends after, or encompasses the missing data points, I need to "fill in" these missing values. Is there a proper term to refer to this concept of filling in data? Imputation is one term, don't know if it is "the" term for it though. I presume there are multiple algorithms & methodologies for filling in missing data (use last measured, using median/average/moving average, etc between 2 known numbers, etc. Anyone know the proper term for this problem, any online resources on this topic, or ideally links to open source implementations of some algorithms (C# preferably, but any language would be useful)

  • Oracle - Determine maximum supported size for regular expression

    - by FrustratedWithFormsDesigner
    I have a regular expression that throws ORA-12733, "regular expression is too long". How do I determine what the maximum supported size is? FYI: the offending regex is 892 characters. It's a generated regex, so I could change how I generate and execute it, but I would like to know what the limits to the max size are before I change how I am generating and executing. (running Oracle 10.2g) UPDATE: If it depends on the actual regex, here's the begining of it (the rest is just the same thing repeated, with different values between ^ and $): (^R_1A$|^R_2A$|^R_3A$|^R_4A$|^R_4B$|^R_5A$|^R_5B$...

  • How can I unit test an Android Activity that acts on Accelerometer?

    - by Corey Sunwold
    I am starting with an Activity based off of this ShakeActivity and I want to write some unit tests for it. I have written some small unit tests for Android activities before but I'm not sure where to start here. I want to feed the accelerometer some different values and test how the activity responds to it. For now I'm keeping it simple and just updating a private int counter variable and a TextView when a "shake" event happens. So my question largely boils down to this: How can I send fake data to the accelerometer from a unit test?

  • Select list value undefined in $(document).ready

    - by C. Ross
    I have the following code, which I want to load values on a selection change, and also do the selection load initially (since FF 'saves' the last value of the drop down under certain circumstances). The select part of the function works correctly, but for some reason when calling load2 directly the value of $('#select1').value is undefined, even though when I check the DOM in Firebug right after load select1.value has a value. How can I run the load2 function when select1.value is ready? $(document).ready(function() { //Setup change hook $('#select1').change(function(event) { //Remove the old options right away $('#select2').find('option').remove(); //Load the new options load2(this.value); }); //Do load for current value load2($('#select1').value); });

  • Right floated div within a liquid-width div. How do I get this to work?

    - by DavidR
    I have a div, within the div is a name in an <h4> tag (it's semantically correct with the layout) and a div with some values describing that <h4> value. I want the nested div to be on the right side, and the only way I can get this to work is a fixed-width container and float: right;. As you can guess, the object breaks when the value of the <h4> causes the nested div to overflow. I've tried min-width, but it ends up stretching to the maximum size of the div containing the container div.

  • HD Crash SQL server -> DBCC - consistency errors in table 'sysindexes'

    - by Julian de Wit
    Hello A client of mine has had an HD crash an a SQL DB got corrupt : They did not make backups so they have a big problem. When I tried (an ultimate measure) to DBCC-repair I got the following message. Can anybody help me with this ? Server: Msg 8966, Level 16, State 1, Line 1 Could not read and latch page (1:872) with latch type SH. sysindexes failed. Server: Msg 8944, Level 16, State 1, Line 1 Table error: Object ID 2, index ID 0, page (1:872), row 11. Test (columnOffsets->IsComplex (varColumnNumber) && (ColumnId == COLID_HYDRA_TEXTPTR || ColumnId == COLID_INROW_ROOT || ColumnId == COLID_BACKPTR)) failed. Values are 2 and 5. The repair level on the DBCC statement caused this repair to be bypassed. CHECKTABLE found 0 allocation errors and 1 consistency errors in table 'sysindexes' (object ID 2). DBCC execution completed. If DBCC printed error messages, contact your system administrator.

  • determine which value produced a hit in SOLR multivalued field type

    - by harschware
    If I have a multiValued field type of text, and I put values [cat,dog,green,blue] in it. Is there a way to tell when I execute a query against that field for dog, that it was in the 1st element position for that multiValued field? Assumption: client does not have any pre-knowledge of what the field type of the field being queried is. (i.e. Solr must provide the answer and the client can't post process the return doc to figure it out because it would not know how SOLR matched the query to the result). Disclosure: I posted to solr-user list and am getting no traction so I post here now.

  • Having difficulty catching postgresql exception in sequel/ruby

    - by mhd
    I have postgresql table that has somekind of unique constraint. I have ruby script that will update this table. The ruby script should be able to switch to UPDATE instead of INSERT when this kind of error occured: PGError: ERROR: duplicate key value violates unique constraint CMIIW, sequel seems cannot catch this exception?? Anyway,sample code below is something that I would like to see to work but apparently not: @myarray.each do |x| fresh_ds = DB["INSERT INTO mytable (id, col_foo) values ('#{x}' ,'#{myhash[x]}')"] result = fresh_ds.insert catch Sequel::Error do fresh_ds = DB["UPDATE mytable set col_foo = '#{myhash[x]} where id = #{x}"] result = fresh_ds.update end end Maybe my ruby code is wrong or I missed something I don't know. Any solution? Thanks. UPDATE: code below works, the error is caught when unique constraint is violated. @myarray.each do |x| begin # INSERT CODE rescue Sequel::Error # UPDATE CODE end end

  • UIImageView is clipping a pixel of the bottom of my UIImage...?

    - by akaii
    I'm not sure what might be causing this, but UIImageView occasionally clips off about a pixel or 2 from the bottom of some square/rectangular UIImages I'm using as subviews for UITableViewCells. These UIImageViews are well within the borders of the cell, so it shouldn't be due to cliptobounds. There seems to be no consistency or pattern to which images are being clipped, nor when they're clipped, other than that it only happens to (or is only noticable in) square/rectangular icons, and only ones that are parented to UITableViewCells (or their subclasses). I'm having trouble reproducing the problem consistently, which is why I haven't posted any code this time. Has anyone encountered something similar to this before? I've encountered a similar bug that involved floating point values for origin/size being interpreted weirdly... but that doesn't seem to be the cause of this particular problem. I don't need a specific solution at this point, I'm just making sure I haven't missed any well-known bugs or documented problems that involve UIImageView.

  • insert into several inheritance tables with OUTPUT - sql servr 2005

    - by csetzkorn
    Hi, I have a bunch of items – for simplicity reasons – a flat table with unique names seeded via bulk insert: create table #items ( ItemName NVARCHAR(255) ) The database has this structure: create table Statements ( Id INT IDENTITY NOT NULL, Version INT not null, FurtherDetails varchar(max) null, ProposalDateTime DATETIME null, UpdateDateTime DATETIME null, ProposerFk INT null, UpdaterFk INT null, primary key (Id) ) create table Item ( StatementFk INT not null, ItemName NVARCHAR(255) null, primary key (StatementFk) ) Here Item is a child of Statement (inheritance). I would like to insert items in #items using a set based approach (avoiding triggers and loops). Can this be achieved with OUTPUT in my scenario. A ‘loop based’ approach is just too slow where I use something like this: insert into Statements (Version, FurtherDetails, ProposalDateTime, UpdateDateTime, ProposerFk, UpdaterFk) VALUES (1, null, getdate(), getdate(), @user_id, @user_id) etc. This is a start for the OUTPUT based approach – but I am not sure whether this would work in my case as ItemName is only inserted into Item: insert into Statements ( Version, FurtherDetails, ProposalDateTime, UpdateDateTime, ProposerFk, UpdaterFk ) output inserted.Id ... ??? Thanks. Best wishes, Christian

  • Iterating over two arrays at a time in Javascript

    - by Ankur
    I want to iterate over two arrays at the same time, as the values for any given index i in array A corresponds to the value in array B. I am currently using this code, and getting 'undefined' when I call queryPredicates[i] or queryObjects[i], I know my array is populated as I print out the array prior to calling this, I haven't put all the other code in as it might be confusing, but if you think the problem is not evident from this I will edit the question: function getObjectCount(){ variables = queryPredicates.length; //the number of variables is found by the length of the arrays - they should both be of the same length queryString="count="+variables; for(var i=1; i<=variables;i++){ alert(queryPredicates[i]); alert(queryObjects[i]); } Thanks

  • Problem saving Text file in database using Hibernate

    - by Marquinio
    I'm having a problem saving large text files to MySQL database. If the text file size is around 5KB it successfully saves. If file is 148KB then I get this error from Hibernate: org.hibernate.exception.DataException: Could not execute JDBC batch update These is the SQL shows by Hibernate: Hibernate: insert into file_table (ID,FILE) values (?, ?) And in my hibernate file I'm using java.sql.Blob to store the file. Anyone knows why it fails to save a file size of 148KB but if I open that same file, cut it down to around 5KB, it will successfully save it? I thought the default limit was I think 2GB? This is weird. Thanks.

  • Function for averages of tuples in a dictionary

    - by Billy Mann
    I have a string, dictionary in the form: ('the head', {'exploded': (3.5, 1.0), 'the': (5.0, 1.0), "puppy's": (9.0, 1.0), 'head': (6.0, 1.0)}) Each parentheses is a tuple which corresponds to (score, standard deviation). I'm taking the average of just the first integer in each tuple. I've tried this: def score(string, d): for word in d: (score, std) = d[word] d[word]=float(score),float(std) if word in string: word = string.lower() number = len(string) return sum([v[0] for v in d.values()]) / float(len(d)) if len(string) == 0: return 0 When I run: print score('the head', {'exploded': (3.5, 1.0), 'the': (5.0, 1.0), "puppy's": (9.0, 1.0), 'head': (6.0, 1.0)}) I should get 5.5 but instead I'm getting 5.875. Can't figure out what in my function is not allowing me to get the correct answer.

  • two HashMap iteration

    - by user431276
    I have two HashMaps and I can iterate both hashmaps with following code Iterator it = mp.entrySet().iterator(); while (it.hasNext()) { Map.Entry pairs = (Map.Entry)it.next(); String firstVal = pairs.getValue(); } Iterator it2 = mp2.entrySet().iterator(); while (it2.hasNext()) { Map.Entry pairs2 = (Map.Entry)it.next(); String SecondVal = pairs2.getValue(); } myFunction(firstVal, SecondVal) Is there anyway to iterate two hashmaps at the same time without using two loops? Currently, I have a method that accepts two parameters and each parameter value is stored in first and second hashmap. I have to iterate first hash then second to get values. I think there must be a good way to do it but I don't know :( P.S: there could be some errors in above code as this is just an example to explain my problem. Each iterator is a method in original program and accept one parameter. I couldn't copy past real time functions as they are HUGE !

I am passing it to function. I hope I made it clear. Thanks

  • defining information out of class

    is there a way to define a value within a class in the __init__ part, send it to some variable outside of the class without calling another function within the class? like class c: def __init__(self, a): self.a = a b = 4 # do something like this so that outside of class c, # b is set to 4 automatically when i use class c def function(self): ... # whatever. this doesnt matter i have multiple classes that have different values for b. i could just make a list that tells the computer to change b, but i would rather set b within each class

  • Is it OK to mixed NumberLong and normal integers in the same field in MongoDB?

    - by Nicholas Tolley Cottrell
    I have been using Morphia to persistent objects from Java. I have also been running some batch processes from the console. I just realised that some values are now stored as NumberLong and number as plain Javascript numbers. I have an index on this field. Everything seems to be ok, but if I query: {f: 100} from the console it still returns the object even if it actually contains {f: NumberLong(100)} Is this true of all the drivers? It is best practice to avoid NumberLong is I can fit the value inside 32-bit? Will I save a lot of data and index space if I convert all NumberLongs to basic numbers?

I can't tell you how many times I want to do the following Make a histogram (exactly Multiset) Get the top N values from the histogram Examples: top 10 URLs, top 10 tags, ... What is the canonical way to do #2 given a Multiset? Here is a blog post about it, but that code is not quite what I want. First, it returns everything, not just top N. Second, it copies (is it possible to avoid a copy?). Third, I usually want a deterministic sort, i.e. tiebreak if counts are equal.

  • Override app.config settings embedded into a MSI?

    - by Seth Petry-Johnson
    I have a .NET solution with an installer project that generates an MSI. One of the projects installed by the MSI contains an App.Config file. It appears that the values of that config file are embedded into the MSI at compile time. Is there a way to override them at runtime? For instance, the App.Config I'm working with sets the URL of a web service that the installer talks to. Is it possible to override this URL at runtime, so that I don't have to recompile the MSI if the URL changes?
