Write design and filter matrices for log-linear model of linkage disequilibrium between two codominant autosomal loci
Description
Write design and filter matrices for log-linear model of linkage disequilibrium between two codominant autosomal loci.
Usage
ld2.model(nall1, nall2, formula="~a1+a2+p1+p2+d")
Arguments
nall1 |
is number of alleles at first codominant locus. |
nall2 |
is number of alleles at first codominant locus. |
formula |
is character string listing terms to be included in model, where a1 denotes allele frequencies for locus 1, p1 the deviation from Hardy-Weinberg expectations for locus1, and d the intragametic allelic association parameters. |
Value
A list with components:
Geno |
is a dummy contingency table showing the expected order. |
s |
is a vector of indices, one for each cell of the full (unobserved)
contingency table, representing the appropriate cell of |
X |
is the design matrix. |
