Text Processing Tools for Turkish E-Commerce Data
Provides several datasets useful for processing and analysis of text in Turkish from an online shopping platform.
Power Analyses for Interaction Effects in Cross-Sectional Regressions
Power analysis for regression models which test the interaction of
two or three independent variables on a single dependent variable. Includes options
for correlated interacting variables and specifying variable reliability.
Two-way interactions can include continuous, binary, or ordinal variables.
Power analyses can be done either analytically or via simulation. Includes
tools for simulating single data sets and visualizing power analysis results.
The primary functions are power_interaction_r2() and power_interaction() for two-way
interactions, and power_interaction_3way_r2() for three-way interactions.

Lexicons for Text Analysis
A collection of lexical hash tables, dictionaries, and word lists.
Nonparametric Models for Longitudinal Data
Support the book: Wu CO and Tian X (2018). Nonparametric Models for Longitudinal Data. Chapman & Hall/CRC (to appear); and provide fit for using global and local smoothing methods for the conditional-mean and conditional-distribution based models with longitudinal Data.
Random Survival Forest for Recurrent Events
Analyze recurrent events with right-censored data and the potential presence of a terminal event (that prevents further occurrences, like death). 'recofest' extends the random survival forest algorithm, adapting splitting rules and node estimators to handle complexities of recurrent events. The methodology is fully described in Murris, J., Bouaziz, O., Jakubczak, M., Katsahian, S., & Lavenu, A. (2024) (< https://hal.science/hal-04612431v1/document>).
Tools for Modelling of Animal Flight Performance
Allows estimation and modelling of flight costs in animal (vertebrate) flight,
implementing the aerodynamic power model described in Klein Heerenbrink et al.
(2015)
Scale Mixture of Normal Distribution in Linear Mixed-Effects Model
Bayesian analysis of censored linear mixed-effects models that replace Gaussian assumptions with a flexible class of distributions, such as the scale mixture of normal family distributions, considering a damped exponential correlation structure which was employed to account for within-subject autocorrelation among irregularly observed measures. For more details, see Kelin Zhong, Fernanda L. Schumacher, Luis M. Castro, Victor H. Lachos (2025)
Irucka Embry's Miscellaneous Functions
A collection of Irucka Embry's miscellaneous functions (Engineering Economics, Civil & Environmental/Water Resources Engineering, Construction Measurements, GNU Octave compatible functions, Python compatible function, Trigonometric functions in degrees and function in radians, Geometry, Statistics, Mortality Calculators, Quick Search, etc.).
Parsing Expression Grammars in Rcpp
A wrapper around the 'Parsing Expression Grammar Template Library', a C++11 library for generating Parsing Expression Grammars, that makes it accessible within Rcpp. With this, developers can implement their own grammars and easily expose them in R packages.
An Improved Version of WA-PLS
The goal of this package is to provide an improved version of WA-PLS (Weighted Averaging Partial Least Squares) by including the tolerances of taxa and the frequency of the sampled climate variable. This package also provides a way of leave-out cross-validation that removes both the test site and sites that are both geographically close and climatically close for each cycle, to avoid the risk of pseudo-replication.
