Yeah, these two are defined to be standard normally distributed, but now the mean and sigma is not 0 and 1. Actually they are interaction coefficients. For example, beta_B_to_tgt is the impact of B on target. I define it to be standard normally distributed, because I assume there are no interaction between these two variables. However, you can see that the mean is 0.794, so can I say they have some correlations in fact?
Edit: Well, I just checked the example code I wrote for you, and these two interaction coefficients were defined as halfnormal. But the cases that I mentioned above do exist for some other coefficients, that is, defined as Standard Normal but actually the mean and std is not 0 and 1.
