Pseudorandom Number Generation with Specific Non-Uniform Distributions
- by carnun
Hello all,
I'm writing a program that simulates various random walks (with differing distributions). At each timestep, I need randomly generated, two dimensional step distances and angles from the distribution of the random walk. I'm hoping someone can check my understanding of how to generate these random numbers.
As I understand it I can use Inverse Transform Sampling as follows:
If f(x) is the pdf of our random walk that has a non-uniform distribution, and y is a random number from a uniform distribution.
Then if we let f(x) = y and solve to find x then we have a random number from the non-uniform distribution.
Is this a feasible solution?
