Ene 11, 2018 — I basically have a panel dataset per country, ID and year. I need to conform France's data to that of all the other observations -- this means that I need to condense those 3 observations into one, where cost = cost if threshold = cost, and LOS = LOS for threshold = LOS.Ago 31, 2016 — Also note that when a variable is referenced in an -if- command, unless you specify otherwise, Stata assumes you mean the value of that variable in the first observation.
