How to get the number of bin and bin edges from chi2gof test

Asked by John

Hi there,

I am fitting a chi squared distribution to data, could some tell me what is the correct syntax to return the number of bins and bin boundaries?

Many thanks

John

Use this kind

[h,p,stats] = chi2gof(...)

Then:

NumberOfBins = numel(stats.O);

And boundaries of i-th bin are:

BoundariesIth = [ stats.edges(i) stats.edges(i+1) ];

Hello,

Thank you - is there anyway to find the optimum number of bins that returns the lowest chi squared statistic? or is it trial and error?
