Gaussian quadrature for bivariate normal distribution

1 message · Niroshan

#
Dear R Users 

I am maximizing  a likelihood function it has two two correlated random
effects which follows bivariate normal distribution. To get the marginal
distribution I want to integrate out with respect to these two correlated
random effects. Does any body know how can I implement gaussian quadrature
to approximate this integral. 

Thanks for taking time
