Subject:      Proc Reg and outputting the Standard error
Content-Type: text/plain; charset="windows-1252"

Hi,

I have a dataset with some longitudinal data.  Using the outest=slopes
command, I can get my numbers from the line fit (regression) to
an output dataset, but I don't know how to include the standard errors.

Any quick ideas??

Here's my (very simple) program so far.


proc reg outest=slopes data=lot2half;
model lnbig=days;
by tind;
run;

                                      Parameter Estimates

                                         Parameter       Standard
       Variable     Label        DF       Estimate          Error    t Value
Pr > |t|

       Intercept    Intercept     1        5.16980        0.26942      19.19
0.0331
       Days         Days          1       -0.01581        0.00718      -2.20


In the output dataset, I can get the days parameter estimate, but I also
need the standard error!!

Thanks

Ingrid
