LD statistics for two SNPs
tbyt(h,n)
h |
a vector of haplotype frequencies |
n |
number of haplotypes |
The returned value is a list containing:
h |
the original haplotype frequency vector |
n |
the number of haplotypes |
D |
the linkage disequilibrium parameter |
VarD |
the variance of D |
Dmax |
the maximum of D |
VarDmax |
the variance of Dmax |
Dprime |
the scaled disequilibrium parameter |
VarDprime |
the variance of Dprime |
x2 |
the Chi-squared statistic |
