I'm using the following syntax to run a regression analysis on a
subset of cases that fall within a range of values (above/below the
cutoff). For some reason it's running the analysis on a random
selection of cases that fall all over the place -- some are within the
range, while others are way out of the range. Any help in finding a
bug in the program is appreciated.
