Error using fitdist. Distribution name 'multinomial' is unrecognized.

I am using 2015b. I read http://uk.mathworks.com/help/stats/fitdist.html and see that it supports "multinomial"

I run

pd = makedist('Multinomial','probabilities',[1/2 1/3 1/6])

pd = 

    MultinomialDistribution

    Probabilities:
            0.5      0.33333      0.16667

Then I run

fitdist([1 10]','normal')

ans = 

    NormalDistribution

    Normal distribution
         mu =     5.5   [-51.6779, 62.6779]
      sigma = 6.36396   [2.83928, 203.075]

Then I try and run

fitdist([1 10]','multinomial')
Error using fitdist (line 146)
Distribution name 'multinomial' is unrecognized.

I do not understand why. Please advise.

Possible work around

function ksd = fitdist2(data)

data(isnan(data)) = [];
u = unique(data);
h = histcounts(data,u);

pd = makedist('Multinomial','probabilities',h./sum(h));

ksd.pd = pd;
ksd.u = u;

%sample: ksd.u(ksd.pd.random)

end

I believe that this may be a documentation error. If you actually look inside the fitdist function, using

edit fitdist

you'll see that 'Multinomial' is not in the list of supported distributions. (But 'Kernel' is not there either, and actually does work.)

Weird. You might want to report to support@mathworks.
