...free manipulation of the covariance matrix (you can only specify a "type", and our "type" doesn't exist). Can R accomplish this? For example: Parameters: B1= Beta 1i B2= Beta 2i G1= Gamma i y = B1 -(B1 - B2) exp { - G1 time} + e the covariance matrix for (B1 [( covB1? covB1B2 covB1G1 B2 ~ covB2B1 covB2? covB2G1 G1) covG1B1 covG1B2 covG1? )] **If we want to specify covG1B1 and make everything else 0's, for example, what would the code look like?
