Error using ==> ProbDistUnivParam.fit at 98
FREQUENCY values must be non-negative integers.
Try to test hypothesis Goodness of fit while trying Poisson dist and getting error Error using ==> ProbDistUnivParam.fit at 98 FREQUENCY values must be non-negative integers.
Please guide

Well, pretty clear error message. Whatever you used for the frequency counts as the input aren't counts (or integers, anyways).
W/o seeing anything else, what else can be said?

bins = 2:4; obsCounts = [2.1 2.2 2.3 2.4 2.5 2.6 2.7 2.8 2.9]; n = sum(obsCounts); pd = fitdist(bins','Poisson','Frequency',obsCounts'); expCounts = n*pdf(pd,bins); I cannot see

...
pd = fitdist(bins','Poisson','Frequency',obsCounts');

obsCounts values surely don't look like integers to me...

this is a very complex data and a very important data set (though just a tiny part of whole data set) if you see no linear line is going to fit on it unless you use predicted values

Which still tells us precisely -- nothing useful.
