Hi Alice,

I am not sure whether I inderstand it properly, but I suspect that you
simply need to round the values. If yes use the function RND. E.g.:

compute var1 = RND(var1 * 1000) / 1000.

Will round var1 to 3 decimal places.

Hello,

Is it possible to save a variable to a specified number of decimal
places? (I don't want to just alter the way the variable is displayed,
but to change the actual value).

The variable I want to do this with is a predicted probability, saved
from binary logistic regression.

(This follows from my previous query on propensity score matching).

Many thanks,

Alice
