Pedro:
You don't hear me say this often.... For this class of problem SAS has a
better procedure than PROC SQL:

data test;
   v0='0'; v1='1'; v2='2';
   output;
run;
proc summary data=test;
  class v0 v1 v2;
  output out=pattern (drop=_type_ _freq_);
run;

Assunto: Re: Hausman Test for comparing fixed vs. mixed models

Yes, but TSCREG has two drawbacks:
1) requires that the data be balanced
2) dummy variables for fixed parameters are explicity estimated and
reported, requiring excessive cpu usage and output

My data (SIPP) is unbalanced and is extremely large (~2.5 million
person-months).

Are there any other ways to get the Hausman test?
Thanks, Matt
