Kogalur [aut, cre] Maintainer: Udaya B. Kogalur Depends: R (>= 4.3.0) Imports: randomForestSRC (>= 3.5.0), parallel, splines, nlme Description: Implements Friedman's gradient descent boosting algorithm for modeling longitudinal response using multivariate tree base learners. Longitudinal response could be continuous, binary, nominal or ordinal. A time-covariate interaction effect is modeled using penalized B-splines (P-splines) with estimated adaptive smoothing parameter. Although the package is design for longitudinal data, it can handle cross-sectional data as well. Implementation details are provided in Pande et al. (2017), Mach Learn .
