You can enter two IF statements in syntax: IF (AGE LT 365) newvar=[formula 1] IF (AGE GE 365) newvar=[formula 2] You can also combine the two in a single formula with two logical conditions: COMPUTE newvar = (AGE LT 365) * [formula 1] + (AGE GE 365) * [formula 2]. In this variant, each logical condition will equal either 0 or 1, and therefore only one formula will be computed for each case.

guys sorry i know this is a basic question but i cant seem to remember how i did this last time. i have one variable, age in days, and another variable, rate. i want to create a formula for rate using values fo other variables. but i have a different formula for when age is < 365 and a different one when it is >= 365. In Compute Variable, there is an option for me to select an 'if statement'. But how do I enter in two if statements, with the different formulas for each. or is there a kind of syntax i can use? thanks so much! -- View this message in context: http://www.nabble.com/compute-variable-using-if-statements-tp18345270p183452 70.html Sent from the SPSSX Discussion mailing list archive at Nabble.com.
