I want to use a higher order statistic on a 2D image segmentation program.
I find this code:
PD = ProbDistUnivParam('normal',Image);
but it's produce an error, "PARAMS must be a numeric vector"
thanks

See http://www.mathworks.com/help/stats/probdistunivparam.html
You are trying to create a ProbDistUnivParam object, which represents a probability distribution. The 2nd argument (which you call 'Image') should be set as per your distribution from http://www.mathworks.com/help/stats/_brn2irf.html

thanks Suneesh,
I found this code in search
pd = ProbDistUnivParam(DISTNAME,PARAMS);
Y = pdf(pd, X);
k = kurtosis(Y);
is 'K' here be the order statistic result?

I want also to know the general equation of higher order statistics to implement it on 2D image. thanks
