 \details{
 
-The function var_test_gwaa tests for difference in genotypic variances. This difference points to presence of possible interaction between the tested SNP 
-and some factor. In the case sqlm test the analysis consists of two stage: firstly the regular GWA id done where regression analysis is performed with 
-covariates specified in the input parameter formula, in the second stage the regression analysis is performed with using residuals from the first stage and 
-a sno as a covariate.
