An example of calculating U and V for MTAR given the genetic effect estimates and their standard errors.
data(beta.example)
A list with 3 sublists:
a list of genetic effect estimates, each sublist is \(m \times K\) matrix for each study
a list of standard errors of genetic effect estimates, each sublist is \(m \times K\) matrix for each study
a SNP correlation matrix for the union of SNPs appearing in all the studies
