The concept behind normal probability plots lies in the fact that if a dataset is normally distributed, the quantiles of the data should match those of a normal distribution. This graphical technique is particularly valuable for detecting outliers, assessing skewness, and identifying patterns that migh...
After doing so, a variable will have a mean of exactly zero but is not affected otherwise: its standard deviation, skewness, distributional shape and everything else all stays the same. After mean centering our predictors, we just multiply them for adding interaction predictors to our data....
