Panos Sousounis
in a panel data context, is there a way of replacing the value of a variable
in period t with the value of the variable in previous periods (t-1,
t-2...etc)? I have a situation where the item is recorded as missing if the
status of the respondent has not changed since first asked. I need a way of
the variable in the current period to take the last valid (non missing)
value of the previous time periods.
