Effect specification for various interaction scenarios. βGE and βGTE are interaction effect parameters for gene-environment and gene-time-environment interactions respectively. Genetic (G) factor coded as 0, 1, and 2 for the number of minor alleles. Environment (E) factor coded as 1 or 0 for presence or absence of the environmental exposure. The tables in each panel present the interaction effect θijk associated with each combination of the genetic (G) and environmental (E) factors
