Help to inputting a pre-defined correlation structure in a Mixed Model
...matrix with the reladness coefficients
(kinship) between all individuals in the study. The K matrix is calculated
outside of R environment, and I'm using it as an input. I'm using the lme
function of the nlme library in R, but I want to know how can I gap the
structures that R offers me (as corrAR1, corrSumm, etc.) as default
structures, because I already have this structure and I only have to
estimate the (sigma g)^2 parameter, possibly using REML. I'm new in the use
of mixed models and I will be very pleased if someone could help me with
this particular question. Thanks a lot in advance...
