How do I control for variables in a linear regression?

Hi!

I'm trying to do a linear regression while controlling for several variables (gender, age, etc). What's the process for doing that?

Thank you so much!

hi,

you just add them in as factors or covariates.

cheers

actually sam, what i've said isn't quite correct. you can easily control for continuous variables by including them as a covariate in a linear regression. but if you want to include 'random factors', you'll need to use the 'mixed effects models' in GAMLj. you can read up on the difference between fixed and random factors, and GAMLj will be the ticket.
