If an in range was not specified to plugin, first will contain one, and last will contain the number of observations in the dataset. SF_nvars() puts the number of variables specified in the varlist in Stata by and egen commands. by and bysort. Many Stata commands can be executed on a group-by-group basis. Earlier we looked at how the Stata by command can be used as a prefix for statistical commands (see help by).

**Now, let’s see the last observation. list if _n==_N ***The command says show the last observation which is 74. **Now let’s see the first and last observations Stata: Extracting values and save them as scalars (and more) 9 R - Keep first observation per group identified by multiple variables (Stata equivalent “bys var1 var2 : keep if _n == 1”) I'd like to create a new variable that takes a value of 1 for all observations in a group if, for any of the observations in the group, X is true. So, for example, my data has the obs , group , and flag variables, and I want to generate the variable grpflag . Most Stata commands are actually loops: do something to observation one, then do it to observation two and so forth. As Stata works through this loop, it tracks which observation it is working on with an internal variable called _n. You are welcome to use this variable in your commands: l if _n==5 egen tag_emrvendor=tag(hospitalid emrvendor) bysort hospitalid: egen n_vendors=total(tag_vendor) But I can't make the frequency table which shows the number of vendors used per hospital 2) EMR functions that a different emrvendor is used per hospital Dear Stata community, I am using Stata 13.1 to analyze survey data.

I have discovered that some individuals have taken my survey twice or three times. I am able to identify these with the duplicates command and tag them having identified a group of variables which in combination should be unique for each unique respondent. I would like to go a However, you may not want to take just the first 100 or so cases, as they may be different in some important way than cases that occur later in the data set. Hence, taking a random sample of the data would be desirable.
