Unique Observations in a variable

[Charlie Johnson]

Hello ! Im new to stata and really enjoy using it so far.

I have a list of about 20,000 observations and want to display and count the unique observations.

I have used codebook then variable name telling me I have 210 unique observations, is there a way to list all the unique observations and count them?

-help duplicates-

duplicates tag *, gen(dupe)
tab dupe
list if !dupe

Welcome to Statalist.

is there a way to list all the unique observations and count them?

Your problem statement suggests to me that you did something like

codebook myvar

which reported that myvar has 210 distinct values. In that case

tab myvar

should do what you want.
