I want to test the goodness of fit of the model , so I use A-D test
I am using matlab 2012a
I got the function from an exchange file.
I try:
paramEsts = gevfit(data); %estimate parameter data 453*1 double
xgrid = linspace(-40,70,453);pdfEst = gevcdf(xgrid,paramEsts(1),paramEsts(2),paramEsts(3));xnew=[data pdfEst'] % 453*2 double
[AD]=AnDarksamtest(xnew,0.05);
but i got an Error:
There must have at least two samples.
and sometimes
one or more samples have no observations.
How I can solve this problem, and calculate the p-value of A-D test?
