Dear statalist
I was wondering if there is a more elegant solution to one below
involving SSC's tsspell by Nick Cox
. which tsspell
c:\ado\plus\t\tsspell.ado
*! 2.0.0 NJC 13 August 2002
The aim is to create an indicator for spells of missing values
completely in between a series (excluding those at the beginning or
the end). (A part in the process of intrapolating a time series,
basically)
I used the following set of commands.
clear
set obs 12
gen var1=_n
tsset var1
input var2
.
.
.
56
.
.
.
95
.
20
.
end
tsspell var2
egen temp=max( _spell)
gen ind=(var2==. & _spell==1)|(var2==. & temp==_spell)| (var2!=.)
Cheers
Abhimanyu
