How can I use the findit command to search for programs and get additional help?
for more information about using findit). Let’s illustrate use of the nmissing and npresent commands using the high school and beyond data file we use in our Stata Classes. use http://www.ats.ucla.edu/stat/stata/notes/hsb1, clear (highschool and beyond (200 cases)) The nmissing command shows us that one of the variables, science, has missing data, and it has 5 missing values. By contrast, the npresent command shows us the number of non-missing values for all of the variables in our data file. From this, we see all of the variables have 200 non-missing observations, except for science that has 195 non-missing observations.
