Hi, I am new to R, so I am unsure of the formula to set up this analysis. I would like to run a linear model with a continuous dependent variable (brain volume) and a continuous independent variable (age) while controlling for a categorical nuisance variable (gender).
Age and brain volume are correlated. There are no gender differences in age but there are significant gender differences in brain volume. Therefore, I would like to control for gender when assessing the association between brain volume and age. Any help would be very much appreciated.
