WebNov 16, 2024 · This leads us to the solution for absorbing states coded by 1: . by id (time), sort: gen byte first = sum (state) == 1 However, this solution is not general enough to cope with nonabsorbing states. If, for example, state is 1 at time 4 but 0 thereafter, sum (state) will be 1 for all times from 4 onward. A more general solution is thus WebFeb 10, 2024 · replace quant=x if year==`i' } The other is to install egenmore (ssc install egenmore), and use the following: egenmore quant=xtile (x), n (4) by (year) I think both are equally efficient, so since you are doing this by year and ID, you should expect it to take a relatively long time to run the commands.

gsort — Ascending and descending sort - Stata

WebYou might be led to the -gsort- command: but that does a decreasing sort in an inefficient manner - it sorts increasing on x, then sorts increasing on minus _n.
