  "Description": "A novel statistical model to detect the joint genetic and\ndynamic gene-environment (GxE) interaction with continuous\ntraits in genetic association studies. It uses\nvarying-coefficient models to account for different GxE\ntrajectories, regardless whether the relationship is linear or\nnot. The package includes one function, GxEtest(), to test a\nsingle genetic variant (e.g., a single nucleotide polymorphism\nor SNP), and another function, GxEscreen(), to test for a set\nof genetic variants. The method involves a likelihood ratio\ntest described in Crainiceanu, C. M., and Ruppert, D. (2004)\n<doi:10.1111/j.1467-9868.2004.00438.x>.",
