Post #1054328

@rlmcelreath Thanks for reminding me of this series of posts. So good! But I think there is a small error: "The influence of B1 [on D] is positive, we know because we simulated the data." But the in the part that generates the data: D <- rnorm( N , 2*B2 + U + 0*M ) No influence of B1. Does the text perhaps assume 1*M?
