Bayesian Modeling of Autoregressive Threshold Time Series Models (TAR)
Identification and estimation of the autoregressive threshold models with Gaussian noise, as well as positive-valued time series. The package provides the identification of the number of regimes, the thresholds and the autoregressive orders, as well as the estimation of remain parameters. The package implements the methodology from the 2005 paper: Modeling Bivariate Threshold Autoregressive Processes in the Presence of Missing Data <DOI:10.1081/STA-200054435>.

Qualitative Palettes with Many Colors (Polychrome)
Tools for creating, viewing, and assessing qualitative palettes with many (20-30 or more) colors.

Generalised Estimating Equations (GEE/WGEE) using ‘Armadillo’ and S4 (gee4)
Fit joint mean-covariance models for longitudinal data within the framework of (weighted) generalised estimating equations (GEE/WGEE). The models and their components are represented using S4 classes and methods. The core computational algorithms are implemented using the ‘Armadillo’ C++ library for numerical linear algebra and ‘RcppArmadillo’ glue.

Causal Mediation Analysis Using Weighting Approach (rmpw)
We implement causal mediation analysis using the methods proposed by Hong (2010) and Hong, Deutsch & Hill (2015) <doi:10.3102/1076998615583902>. It allows the estimation and hypothesis testing of causal mediation effects through ratio of mediator probability weights (RMPW). This strategy conveniently relaxes the assumption of no treatment-by-mediator interaction while greatly simplifying the outcome model specification without invoking strong distributional assumptions.
