One degree of freedom Chi-squared test of allelic counts
A matrix of genotype values coded as 0, 1 or 2 for homozygous major, heterozygous, or homozygous minor, respectively. Rows are subjects and columns are SNPs. May be created with method as.double.snp.data from the GenABEL package.
A vector of disease phenotypes, diseased = 1, non-diseased = 0
This function returns a vector of chi-squared, one degree of freedom, statistics for the allelic test of association. The length of this vector is the number of SNPs.
