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 Z3, Y4 < Inf) = P(Y1 <

Try setting exclude=NULL if you think that the NA's need to be considered as a value. The default is to exclude both NaN and NA. -- David Winsemius -- Original message -- From: "Farley, Robert" > I presume the behavior below (no Connector values in the second
