I do understand the advantages of standardizing regression predictors to get standardized coefficients, in order to interpret the coefficients better. However, as I was reading multiple pages online, I figured that some people do standardize both predictor AND outcome to get standardized coefficients. It doesn't make sense to me. I am OK with standardizing predictors, but when the outcome is standardized too, we are predicting another value (not the actual Y). Is that right?
I also do accept the regression results when the predictors are STANDARDIZED and the outcome is CENTRED. However, not the regression results when the predictors are STANDARDIZED and the outcome is STANDARDIZED too.
Is that correct?
