Problem Note 17646: PROC ALLLELE reports incorrect statistics with HAPLO=NONEHWD if
individuals have missing alleles
The correlation coefficient and chi-square goodness-of-fit test used to
test markers for Hardy-Weinberg Equilibrium (HWE) are incorrectly
computed in PROC ALLELE when the HAPLO=NONEHWD option is specified on
the proc statement and individuals have missing alleles present.
When HAPLO=NONEHWD, the HWE coefficients that are used in the
denominator of the correlation coefficient and chi-square test should be
calculated using only individuals that are genotyped at both markers in
the pair. Currently, all individuals genotyped at the single marker are
being used.
There is no circumvention for this problem.
