Simulated data of SNPs
simSNP is a data.frame containing a bivariate outcome as in a case-control study, a continous covariate
and 10 simulated SNPs. SNPs 1 and 2 have an interaction effect on the outcome. Penetrances
are specified as in model 1 of Ritchie et al.(2003)
simSNPcont is a data.frame containing a continuous normally distributed outcome and 10 simulated SNPs, where SNPs 1 and 2 have an interaction effect on the outcome.

simSNP is a data frame with 400 observations on the following 12 variables.
||Outcome: 1=case, 0=control|
||SNP genotype data 1|
||SNP genotype data 2|
||SNP genotype data 10|
SNP values are coded as: 0=common homozygous, 1=heterozygous, 2=variant homozygous.
simSNPcont has a continous outcome and the same SNPs.
