Stata not using all observations

[Peter Sutton]

how to delete a post?

[Rich Goldstein]

my guess, based on your very limited info, is that some variables have missing data and are thus excluded; use -misstable- or the user-written -missings- to find out; see

help misstable

if you want to use -missings-, you will need to download and install; use -search- or -findit- to locate and install
