I want to perform multiple linear regression on my variables; since my dependent variable was negatively skewed, I reflected it and then I log transformed it. My independent variables was positively skewed, so I only log transformed them.
My first question is: after performing multiple linear regression on my variables, should I interpret results adversely?
I mean: if an independent variable has a positive beta, I say it has a negative effect on dependent variable; and if an independent variable has a negative beta, I say it has a positive effect on dependent variable?
My second question is: my adjusted $R^2$ is $0.35$, is that good enough to say that my model is acceptable?
