WebStata treats a missing value as positive infinity, the highest number possible. So, when we said list if rep78 >= 4, Stata included the observations where rep78 was ‘. ' as well. If we wanted to include just the valid (non-missing) observations that are greater than or equal to 4, we can do the following to tell Stata we want only ...
