GenerateRandomPositiveDefiniteMatrix

<p>Generate postive definite matrix using QR decomposition</p>

Analyzes the phenotypic evolution of species
of hybrid origin on a phylogenetic network. This package can detect the hybrid
vigor effect, a burst of variation at formation, and the relative portion of
heritability from its parents. Parameters are estimated by maximum likelihood.
Users need to enter a comparative data set, a phylogeny, and information on gene
flow leading to hybrids. See Jhwueng and O'Meara (2017)
