Number of marker SNP sets with adjacent interactions included
Number (proportion) with significant improvement in log-likelihood
Number (proportion) with improvement in AIC
Results of whether including adjacent interaction improves modelling of marker haplotype frequencies. Columns refer to 1) the density of marker SNPs (in terms of 1 marker SNP per x SNPs in dataset generated by COSI); 2) the number of sets (out of 1000) where adjacent interactions were not fully predictable from main-effects; 3) the number of sets with adjacent interactions included where they resulted in a significant improvement in model fit (at 5% significance level); 4) the number of sets where including adjacent interactions reduced the AIC.
