Penalized Elastic Net S/MM-Estimator of Regression (pense)
Robust penalized elastic net S and MM estimator for linear regression. The method is described in detail in Cohen Freue, G. V., Kepplinger, D., Salibian-Barrera, M., and Smucler, E. (2017) <https://…/PENSE_manuscript.pdf>.

Comparison of Algorithms with Iterative Sample Size Estimation (CAISEr)
Functions for performing experimental comparisons of algorithms using adequate sample sizes for power and accuracy.

Fitting Dynamic Frailty Models with the EM Algorithm (dynfrail)
Fits semiparametric dynamic frailty models according to the methodology of Putter and van Houwelingen (2015) <doi:10.1093/biostatistics/kxv002>. Intermediate models, where the frailty is piecewise constant on prespecified intervals, are also supported. The frailty process is taken to have a specific auto-correlation structure, and the supported distributions include gamma, inverse Gaussian, power variance family (PVF) and positive stable.
