I have country/year panel data. I would like to drop some observations according to specific values of some variables but I would like to do so according to the value for the first year in which I have data for the country.
The problem I am facing is that I have an unbalanced panel so I cannot use a command of the sort:
Code:
gen temp=1 if value<x & year==2000
My dataset is of the following form:
| Country | Continent | Year | agprod | drought |
| ABW | LAC | 1972 | 13413513 | 0 |
| ABW | LAC | 1973 | 15213523 | 1 |
| ABW | LAC | 1974 | 13513513 | 1 |
| ADO | WEOFF | 1972 | 353413 | 0 |
| ADO | WEOFF | 1973 | 234233 | 0 |
