I would like to fill in for missing dates in the following data. Additionally, I would like to
keep the former value of the wt-variable on the filled in dates. The first part went well while I have
problems with the last step. Variations over lags have not worked */
Using lags it best to make them unconditional. You have placed a lag cal within multiple IF clauses.
Better would be BEFORE all of the if:
Lagwt = Lag(wt);
then replace your
wt= lag(wt)
with
wt = lagwt;
and then drop the Lagwt variable.
Note that another function similar to lag is DIF. So you can address Dif(daymonthyear) in the same manner as Lag, with the same warning about conditional use.
