Dear All, let E(Y | t, b, theta) be the conditional expectation of Y where b is a vector of random effects , theta is a vector of fixed effects and t is the time of observation (t =1,2, ...,n). I wonder if nlme has a function to compue E(Y | t, theta). I know that it can be done by approximating the integrals over b of E(Y | t, b, theta). But I am wondering if nlme has a function to do that directly. Thank you, Bernard
