average

My current query reads:

SELECT entry_id, user_id, cat_id, AVG( rating ) as avg_rate
FROM entry_rate
WHERE 1
GROUP BY entry_id

cat_id relates to different categories: 1, 2, 3 or 4

Is there a way I can find the maximum average for each user in each category without setting up an additional table? The return could potentially be 4 maximum avg_rate for each user_id
