I need to filter out cases which contain a certain number (which served as a marker in my imaging program) before replacing the missing values in my dataset. However, I noticed that the missing value will be filtered out as long as I activate the filter function (in this case, Select cases, if D1 NE 6979). After switching on the filter, I conducted a missing value replacement by interpolation (>transform>replace missing value>linear interpolation).
The missing values appeared nicely replaced eventhough those cases with missing values were 'slashed' (indicating that this case is filtered). May I know if it's still workable if my missing values are replaced in this manner (with the filter on)? I am just worried that some hidden steps may have taken place and the missing values are not being replaced via the 'rtg way'.
THANKS in advance!
