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?
