This week Eamonn send us the following question about the Compute function:
When using transfor/compute – say to create a construct from a set of Likert
Scale items – does SPSS save the formula used to create the new variable, or
is it lost once you compute?
SPSS does not save the formula in your data file. It does keep the formula in mind if you keep SPSS open. So if you want to use the same formula again, but than with different variables for example, you can open the Compute screen again, and there your old formula is. But if you close SPSS and open it again, the formula will be gone.
