.- help for ^genhw^ .- Hardy-Weinberg equilibrium test ------------------------------- ^genhw^ all1 all2 [weight] [^if^ exp] [^in^ range] [^,^ ^bin^var^] ^genhwi^ #AA #Aa #aa [^,^ ^l^abel(genotypes) ^bin^var^] ^fweight^s are allowed; see help @weights@. Description ----------- ^genhw^ estimates allele, genotype frequencies and disequilibrium coefficients for codominant traits and performs asymptotic Hardy-Weinberg (HW) equilibrium tests. In the case of two alleles it also calculates an exact HW significance probability. ^genhw^ expects the data to be in long format. That is, each observation contains the two allele values at the locus being examined (all1 and all2). Allele values can be numeric or string. ^genhwi^ is the immediate form of ^genhw^ using the genotypic counts on the command line; where #AA, #Aa and #aa are the counts for the AA, Aa and aa genotypes. Note that this immediate command only works for biallelic loci. Options ------- ^binvar^ specifies that binomial standard errors be reported. These standard errors are calculated assuming that the population is in Hardy-Weinberg equilibrium. By default standard errors that do not requirer this assumption are reported. ^label()^ specifies labels to be use in the output of the genotype frequency table. In the case of a multiallelic locus this option is ignored.
