For the quadratic equation regression (y=a+x+x2+u) can we take log transformation of independent (x) variable?
Yes, you could log. If you have outliers in your independent variable, a log transformation could reduce the influence of those observation.
I am trying to analyse data from a survey examining what variables affect teachers perceived barriers to incorporating technology into their classroom. I have 5 predictor variables however my DV...
