A Kiefer-Wolfowitz procedure for ML estimation of a Gaussian model with dependent mean and variance components and weighted longitudinal data. This version assumes a general bivariate distribution for the mixing distribution. The defaults use a rather coarse bivariate gridding.
WGLVmix(y, id, w, u = 30, v = 30, ...)A vector of observations
A strata indicator vector of the same length
A vector of weights
A vector of bin boundaries for the mean effects
A vector of bin boundaries for the variance effects
optional parameters to be passed to KWDual to control optimization
A list consisting of the following components:
midpoints of mean bin boundaries
midpoints of variance bin boundaries
the function values of the mixing density.
