Hi Guys,

I am trying to calculate the square root of the variance of the residual of a regression.

Basically if the regression is the following:

R= a+ b1.MKT+ b2.SMB + B3.HML+ B4.UMD + E

Then I am trying to compute X, where

X = √ var(E).


PS: Also, can the result be stored in a SAS dat. file, because I need to merge it to the original data set later on.


Thanks a lot for the help guys! Appreciate it!

Proc reg will give you the root mean square error as part of the fit statistics. You can output them in dataset myStats :

proc reg data=myData plots=none;

     model R = MKT SMB HML UMD;

ods output FitStatistics=myStats;

run;

What is ANOVA?

ANOVA, or Analysis Of Variance, is used to compare the averages or means of two or more populations to better understand how they differ. Watch this tutorial for more.
