1. THE USER WANTS TO POOL ALL SUBFILES FOR
SUBSEQUENT ANALYSIS, E.G., RUN SUBFILES ALL
2. THE USER WANTS TO POOL BOTH THE 1982 (1987) SUBFILES, Y82 (Y87) AND Y82B (Y87B), THE TRADITIONAL
CROSS-SECTIONAL SUBFILE AND THE BLACK OVERSAMPLE
SUBFILE.
3. THE USER WANTS TO ANALYZE ONLY BLACKS FROM
THE POOLED 1972-1991 SAMPLE.
IN THESE THREE SITUATIONS IT IS NECESSARY TO WEIGHT
THE DATA BY THE VARIABLE OVERSAMP.
IF THE USER IS ANALYZING ONLY BLACKS FROM THE Y82 (Y87) AND
Y82B (Y82B) SUBFILES, THE USE OF THE WEIGHT IS NOT NECESSARY.
