Lineair interpolation when using a filter


New Member

I want to replace missing values by lineair interpolation. My cases are a combination of a country and a year (Austria 1990, Austria 1991, et cetera). In order to prevent that a missing value is calculated bij the value of another country and the intended country I want to do the lineair interpolation seperate for each country. However, when I make a filter for a specific country and then use the RMV command, the lineair interpolation is still done for all countries. How can I fix this problem?


IF (iso2c="AU") Austria=1.
Filter by Austria.
RMV / VarNew = LINT (VarOld).
