LEGIT: Latent Environmental & Genetic InTeraction (LEGIT) Model

Constructs genotype x environment interaction (GxE) models where G is a weighted sum of genetic variants (genetic score) and E is a weighted sum of environments (environmental score). This approach has greatly enhanced predictive power over traditional GxE models which include only a single genetic variant and a single environmental exposure. Gene x gene interactions (GxG) and environment x environment interactions (ExE) can be incorporated into the genetic and environmental scores. Any standard model formula can be used, it doesn't have to be a two-way interaction model. Although this approach was made for GxE modelling, the genetic score doesn't need to contain genetic variables and the environmental score doesn't need to contain environmental variables, therefore this approach is highly flexible. A paper discussing the method used for estimating the weights should be released as pre-print and sent for peer- review before Summer 2017.
