**Methods for Transition Probabilities** (**presmTP**)

Provides a function for estimating the transition probabilities in an illness-death model. The transition probabilities can be estimated from the unsmoothed landmark estimators developed by de Una-Alvarez and Meira-Machado (2015) <doi:10.1111/biom.12288>. Presmoothed estimates can also be obtained through the use of a parametric family of binary regression curves, such as logit, probit or cauchit. The additive logistic regression model and nonparametric regression are also alternatives which have been implemented. The idea behind the presmoothed landmark estimators is to use the presmoothing techniques developed by Cao et al. (2005) <doi:10.1007/s00180-007-0076-6> in the landmark estimation of the transition probabilities.

**Alternating Direction Method of Multipliers to Solve Dense Dubmatrix Problem** (**admmDensestSubmatrix**)

Solves the problem of identifying the densest submatrix in a given or sampled binary matrix, Bombina et al. (2019) <arXiv:1904.03272>.

**Interface to ‘TensorFlow Probability’** (**tfprobability**)

Interface to ‘TensorFlow Probability’, a ‘Python’ library built on ‘TensorFlow’ that makes it easy to combine probabilistic models and deep learning on modern hardware (‘TPU’, ‘GPU’). ‘TensorFlow Probability’ includes a wide selection of probability distributions and bijectors, probabilistic layers, variational inference, Markov chain Monte Carlo, and optimizers such as Nelder-Mead, BFGS, and SGLD.

**Cohort Data Analyses** (**cohorttools**)

Functions to make lifetables and to calculate hazard function estimate using Poisson regression model with splines. Includes function to draw simple flowchart of cohort study. Function boxesLx() makes boxes of transition rates between states. It utilizes ‘Epi’ package ‘Lexis’ data.

**Easily and Rapidly Generate Raster Image Data with Support for ‘Plotly.js’** (**rasterly**)

Easily and rapidly generate raster data in R, even for very large datasets, with an aesthetics-based mapping syntax that should be familiar to users of the ‘ggplot2’ package. While ‘rasterly’ does not attempt to reproduce the full functionality of the ‘Datashader’ graphics pipeline system for Python, the ‘rasterly’ API has several core elements in common with that software package.
