fitComponentModel | fitComponentModel Fit the estimated variance components of a model to covariance data
fitPedigreeModel | Fit an OpenMx pedigree model to observed data
fuseTwins | Fuse MZ twin pairs in a pedigree dataset for path tracing This function identifies MZ twin pairs in the pedigree dataset and merges their IDs for path tracing purposes. The second twin in each pair is made a founder (with NA parents), and all children of the second twin are redirected to the first twin. This allows for correct relatedness calculations without diagonal or downstream artifacts.
