Hello everyone,

I need to fit a bivariate normal regression model to a dataset where the
same covariate (say, X) influences two separate but correlated responses
(say, Y1 and Y2). So, the bivariate
model would look like :

Y1 = a1 + b1*X + e1
Y2 = a2 + b2*X + e2

where e1 and e2 are error terms which can be correlated. Is there any
package in R which can help me fit this model ? Any help will be
appreciated.

Best regards,
Dhiman Bhadra
