29 Mar 2014 gmregress Geometric Mean Regression (Reduced Major Axis Regression). Author: Antonio Trujillo-Ortiz

The slope sign bug was efficiently corrected thanks to the valuable suggestions given by Holger Goerlitz and Joel E. Cohen. Yes, a negative slope are always negative!

Hi Faith,
No. It does not support missing values.

Hi. I tried to use a RBF Network to fit my data. In this case, should the Design Matrix H my input data?

I mean: D = [H;y]?

Thanks

True about the NaNs when variance of variables is null (in T2Hot1.m). Well done though!

04 Sep 2014 gstd Standard deviation of a grouped sample. Author: Antonio Trujillo-Ortiz Wajahat

Excellent. A very quick and tool to calculate the Std.Dev. of grouped data or histograms.
Its strange that Matlab Statistics Toolbox does not include a function for this. Or at least I could not find one.
