Dear forum, we have a 2 dimensional normal distribution of (x, y) which is consistent with a linear regression modell of type
y = ax + b. It has a heteroscedastic variance. Is there a straight and simple way with R to get the variance of the marginal distribution W(y|x=xi) where xi may be randomly chosen? Maybe a single line command?
