%description
Provides functions to conduct a model-agnostic asymptotic hypothesis test
for the identification of interaction effects in black-box machine
learning models. The null hypothesis assumes that a given set of
covariates does not contribute to interaction effects in the prediction
model. The test statistic is based on the difference of variances of
partial dependence functions (Friedman (2008) <doi:10.1214/07-AOAS148> and
Welchowski (2022) <doi:10.1007/s13253-021-00479-7>) with respect to the
original black-box predictions and the predictions under the null
hypothesis. The hypothesis test can be applied to any black-box prediction
model, and the null hypothesis of the test can be flexibly specified
according to the research question of interest. Furthermore, the test is
computationally fast to apply as the null distribution does not require
resampling or refitting black-box prediction models.
