I am really confused. I performed a partial regression (linear) and plotted all partial plots (option in SPSS-linear regression--plots). I end up with 3 plots with negative values in the x and y axis. Now I do not know how to interpret this... Are thes values residuals from the seperate regressions of the covariate and if so in x or y direction? Is there a better option to plot partial correlations?
Thanks for any support!
