\title{Mean and Variance information for full-sibs, half-sibs, first-cousins}
\description{
  Computes theoretical mean and covariance matrix for k0 vs. k1 ibd coefficients
  for full-sib relationship along with inverse and eigenvalues/vectors of
  the covariance matrix. 

Computes theoretical means and variances for half-sib 
  relationship and for first-cousin relationship.
