The function computes the critical constants defining the UMPU test for
one-sided equivalence of the population distribution of a SNP, to a distribution
being in Hardy-Weinberg equilibrium (HWE).
A substantial deficit of heterozygotes is defined to occur when the true value of the
parametric function ω = \frac{π_2/2}{√{π_1π_3}} [called relative excess
heterozygosity (REH)] falls below unity by more than some given margin δ_0.
Like its two-sided counterpart [see the description of the R function gofhwex],
the test is conditional on the total count S of alleles of the kind of interest.
