Stata tag first observation

Starting with Stata 8, the duplicates command provides a way to report on, give examples of, list, browse, tag, or drop duplicate observations. This FAQ is likely only of interest to users of previous versions of Stata. Case 1: Identifying duplicates based on a subset of variables. You wish to create a new variable named dup This Stata FAQ shows how to check if a dataset has duplicate observations. There are two methods available for this task.

_n is 1 in the first observation, 2 in the second, 3 in the third, and so on. _N is Stata notation for the total number of observations. Let’s see how _n and _N work.

2007-11-23 I am using STATA command xtabond2 and system GMM for my very first project. According to Arellano and Bond (1991), Arellano and Bover (1995) and Blundell and Bond (1998), two necessary tests 2019-02-11 2016-05-13 Whichever data type was there first is what Stata will assume is correct. it will start with the first observation within the group (index number [1]), generate a new variable which tags records where the individual had a concurrent infection with more than one organism on the same specimen date. [Note: The gdplag and gdpgrowth for the first observation (_n==1) will be missing since observation [_n-1] does not exist for _n==1.] Make sure, however, that you refer to the right neighbor! For example, if you are calculating the growth rate of variable gdp between 1999 and 2000, gdp must be in order such that the gdp subscripted by [_n-1] is the gdp for 1999. 2016-06-21 duplicates tag id, I only want to keep the observation with the first registration post surgery, Stata's result reports effect size just in two decimals.

It tags just 1 observation in each distinct group defined by varlist. When all observations in a group have the same value for a summary variable calculated for the group, it will be sufficient to use just one value for many purposes. 2007-11-23 I am using STATA command xtabond2 and system GMM for my very first project.

The second command adds those values up by -country-. > Adding 1s, one for each instance, is usually just called counting.
