Speaking Stata: Making it count

The count command has one simple role, to count observations in general or that satisfy some condition(s). This task can be useful when some larger problem pivots on counting, especially if count is used with a loop over observations or variables. I use various problems, mostly of data management, as examples. I also make comparisons with the use of N, summarize, and egen for the same or similar problems.
