Determining optimal number of bins for chi squared distribution

11 views (last 30 days)
Hello,
I am applying a chi squared distribution to histogram. Is there any way in matlab to determine the optimal number of bins to get the lowest chi squared (X2) statistic?
The Chi-square goodness-of-fit test function does not necessarily tell you the optimal number of bins to use, or does it?
Many thanks
John

More you have, better will be. if you have a great number of data you can go far with stand deviations because you will always have the product Prob*N_tot big enough
