Abstract:
|
Discovering statistical interactions is an essential step towards understanding the complex relationships among explanatory variables. We propose a new approach for detecting statistical interactions in data by fitting an additive neural network. Our method is based on comparing the performance between the full model and the restricted model, where the full model includes all potential variables while the restricted model excludes the pre-specified interaction terms. Our testing method targets at functional interactions and is free of distributional assumptions. In numerical experiments, we demonstrate that our method can accurately detect interactions under synthesize and real data.
