Estimate linkage disequilibrium between two codominant autosomal loci
Description
Fits a log-linear model for allelic association between two codominant autosomal loci. Measures of LD are odds ratios.
Usage
ld2(locus1, locus2)
Arguments
locus1 |
is a character vector containing the genotypes at the first locus, or a RxC contingency table of genotype counts. |
locus2 |
is a character vector containing the genotypes at the second locus. |
Value
m0 |
base model |
m1 |
estimating LD coefficient(s) assuming HWE |
m2 |
testing HWE at locus 1 |
m3 |
testing HWE at locus 2 |
m4 |
estimating LD and HWD coefficient(s) |

rownames(MNS)<-c("M/M","M/N","N/N")
