Help add functionality to MATLAB

Dear MATLAB community,

Please help add custom Distribution Fitting Functions & Negative Log-Likelihood Functions to the statistics toolbox that matlab provides.

I am looking at the documentation, as seen here,
http://www.mathworks.com/help/toolbox/stats/bqt29ct.html,

and here,
http://www.mathworks.com/help/toolbox/stats/f4218.html#bqt4w61

You will notice that MATLAB does not provide Distribution Fitting Functions & Negative Log-Likelihood Functions for the "continuous distributions (statistics)" set of distributions, as they do for the "continuous distributions (data)" set of distributions.

This is functionality that could be used if a data set had a non-central chi squared distribution, for example. This can and does happen in the world of data. The non-central chi squared distribution is NOT only a distribution used for statistical analysis.

I would try to do this myself, but I do not want to screw it up, and it is slightly above my head to create this properly. I implored the Mathworks to consider adding this functionality over 2 years ago and it has not been looked at.

Please help improve MATLAB.

I just noticed that the first link is not working properly because of the comma at the end of the link. So, just use this link:

The Mathworks may or may not see this. Your best bet is to send an
email request to support@mathworks.com or call them on the phone.

Sorry, I reread is and noticed you already did ask them. You can ask
again. Sometimes your request doesn't make it into the very next
version after you ask. I've had requests finally come in two or three
versions later. Or else write it yourself or hire a more skilled
person to write it for you.
