A data smoothing approach to explore and test gene-environment
interaction in case-parent trio data
Description
The package contains functions that 1) estimates
gene-environment interaction between a SNP and a continuous
non-genetic attribute by fitting a generalized additive model
to case-parent trio data, 2) produces graphical displays of
estimated interaction, 3) performs permutation test of
gene-environment interaction; 4) simulates informative
case-parent trios.
