A better and simpler chisquare test

Hacker News - Sat, 04/26/2025 - 6:02am

The idea is so simple that surely someone must have imagine it before. Just an example suffice: consider the experiment of throwing a dice, this can be seen as five different independent experiments counting the numbers in the remaining cases and applying the normal approximation to the binomial, so that for example in a dice the probabilies are 1/6, 1/5, 1/4 .... and you sum those (oi - restpi)/(rest*pi*qi) where pi are the updated probabilies and rest are the remaining number in each case. The sum is are chisquare with n-1 dof. In the examples in wikipedia the numbers are very different for the first example but similar for the second. Bayesian intuition or common sense implies that the n-1 experiment are independent,

I should write this better, to honor the HN crowd, but today don't have the time nor the like, neither I will be famous
