Extended variable selection approaches to jointly model main and interaction effects from high-dimensional data orignally proposed by Hao and Zhang (2014) and extended by Gosik and Wu (2016). Based on a greedy forward approach, their model can identify all possible interaction effects through two algorithms, iFORT and iFORM, which have been proved to possess sure screening property in an ultrahigh-dimensional setting.

formula |
an object of class formula, or one that can be coerced to that class,: a symbolic description of the model to be fitted. The details of model specification are given under 'Details'. |
data |
data.frame of your data with the response and all p predictors |
heredity |
a string specifying the heredity to be considered. NULL, weak, strong |
higher_order |
logical TRUE indicating to include order-3 interactions in the search (default FALSE) |
Runs the iFORM selection procedure on the dataset and returns a linear model of the final selected model. The model is of an R object of class "lm"
a summary of the linear model returned after the selection procedure
