I am fitting a distribution to data and trying to perform chi-square goodness-of-fit test.
I have calculated the likelihood values and wanted to perform goodness-of-fit test
However, having read through the Help menus, I tried to run the script below but am getting error:
x=claims; [h,p,stats] = chi2gof(X,'cdf','weibull',nparams,2)
where claims is 1xn vector
I do not know where I have gone wrong and would appreciate anyone's assistance to resolve this.
Also, I needed the script to calculate chi-square test statistic for Negative Binomial distribution.
Much thanks in advance

I believe you got an answer separately on comp.soft-sys.matlab, but:
Try @nbincdf to use the negative binomial cdf.
