t values for regression model coefficients

I used the regress function to model fit in the form of y = a1+a2*x2+a3*x3. How do I find the standard deviations and the t-values for the coefficient parameters a1, a2, and a3 in MATLAB?

From the documentation "help regress":

[B,BINT,R,RINT,STATS] = REGRESS(Y,X) returns a vector STATS containing, in the following order, the R-square statistic, the F statistic and p value for the full model, and an estimate of the error variance.

Thanks for the suggestion. However, when I tried this in MatLab, I only get three values in my STATS vector. I can't tell which three of the 4 values listed I am actually getting.

I find this odd, to be sure. My cut&paste from the documentation is from version R2010b, and I get four values in the stats output.

Are you using an older version? If so, you should rely on your version of the documentation, which I hope would accurately correspond to what you are seeing in output. If not, that is something to bring up with MathWorks suppor.t
