BCodifSIS: Ball-Codifference Sure Independence Screening

Computes Ball-codifference scores and performs sure independence screening for high-dimensional predictors. The score combines random-ball empirical probabilities with a bounded local codifference weight based on trigonometric characteristic-function contrasts. The functions are intended for marginal screening when moment-based dependence summaries may be unstable or undefined, such as in heavy-tailed data. The implemented methodology is described in Rezapour and Maroufy (2026) "Ball-Codifference Screening for Heavy-Tailed Predictors" <doi:10.48550/arXiv.2607.20821>.
