In the regress function what is the estimate of the error variance returned within stats

I am using the regress function from the Statistics Toolbox. It returns a parameter called stats, which includes "an estimate of the error variance", according to the documentation. I want to know how this "estimate of the error variance" is calculated. Also is this the RMS?

Thank you very much

Cheers

Error variance is the square of the root mean square error (RMSE). So, to be clear, it is RMSE^2.

You can verify this for yourself by typing

edit regress

and seeing the calculation of s2, which is the last element of the stats vector.

please give us an example, i don't understand your explanation of error variance
