Applying multiple regression results to new data

Postby rustinhoffman » Sat Dec 05, 2015 2:57 pm

My study involves testing infants at multiple time point using multiple tests.

I used a multiple regression to establish which behavioural variables could predict severity of outcome score at the end of the testing. So i am testing infants at 14 months and seeing which scores from each variable could predict better or worse scores at 24 months.

my model works fine, but now I want to use this regression model to see whether it can predict 24m outcome on a new dataset with new infants that have been tested on the same IV' s and DV's.


Does anyone know how I might go about doing this?


Thank you

so basically, you want to use the regression weights and see if those same weights can predict the outcomes at T2?
You can just create a variable with the values of the weights and calculate the formula and outcome yourself maybe?

You can also export the regression weights to another dataset (using OMS) and merge them in again if you want everything automated, but just creating the variables yourself (if you have only 1 test to run and not many) might be easier.
