Re: [R] Normal cdf modified function

I would think this could be approached by segmenting the probability volume using identities such as these: P(Y1 Z1, Y2 Z2, Y3 Z3, Y4 Z4) + P(Y1 Z1, Y2 Z2, Y3 Z3, Y4 Z4) = P(Y1 Z1, Y2 Z2, Y3 Z3, Y4 Inf) and P(Y1 Z1, Y2 Z2, Y3 Z3, Y4 Inf) + P(Y1 Z1, Y2 Z2, Y3 Z3, Y4 Inf)
