I'm using the stepwisefit function between the predictor variable X(69,8) and the response variable y. Each column in X (predictor) is previously standardized as well as the response variable. After applying the function as follows: B = stepwisefit(X,y), only two predictors appears to be in the model given the statistical significance by default (0.05). The problem is that I expect these coefficients to range between +1 and -1 due to previous standardization, but the values are 2.0251 and -2.2983. I need them to be standardized so that I can calculate the percentage of explained variance by each one.
Thanks in advance for your help!
