generate_gaussian

internal

A flexible framework combining
variable screening and random projection techniques for fitting ensembles of
predictive generalized linear models to high-dimensional data.
Designed for extensibility, the package implements
key techniques as S3 classes with user-friendly constructors,
enabling easy integration and development of new procedures for
high-dimensional applications. For more details see
Parzer et al (2024a) <doi:10.48550/arXiv.2312.00130> and
Parzer et al (2024b) <doi:10.48550/arXiv.2410.00971>.
