MATLAB: How can I use higher order statistics in an image

higher order statisticsImage Processing ToolboxStatistics and Machine Learning Toolbox

 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

there is a pdf file have an explanation of HOS with matlab.

MATLAB: Nakagami Distribution

Hi, If you have the Statistics Toolbox, you can use histfit() with the 'nakagami' option.

You can also use mle() with the 'nakagami' option to get the maximum likelihood estimates of the parameters of the Nakagami distribution.

MATLAB: How to evaluate kth moment of a distribution created using ProbDistUnivParam

The following is one simple way to calculate kth moments (and higher-order statistics in general) once a probability distribution is created using PROBDISTUNIVPARAM.

Assuming you have a probability distribution pd, for instance, obtained as follows:

pd = ProbDistUnivParam(DISTNAME,PARAMS);

It suffices to use the method PDF (which is part of the ProbDistUnivParam class) to obtain the probability density function (PDF) for the ProbDist object. For example:

Y = pdf(pd, X);

where X is a numeric array of values where you want to evaluate the PDF.

Then one could use the various MATLAB functions available to calculate higher-order statistics. For instance, kurtosis can be calculated as follows:

k = kurtosis(Y);
