st: Re: Filling gaps???

["Michael Blasnik" <michael.blasnik@verizon.net>]

I haven't seen any other one line solutions, so thought I'd post as well:

by HouseholdID: egen HHinfected=max(Infected)

or, if there are no missing values in Infected:

by HouseholdID (Infected): gen byte HHinfected=Infected[_N]
