Implements the dynamically weighted modified maximum likelihood
 ridge (DWMMLR) regression estimator, a robust and multicollinearity-aware
 linear regression estimator that combines the DWMML3 weighting procedure of
 Sazak (2019) <doi:10.1080/00949655.2019.1571060> with ridge penalization to
 address both outlier sensitivity and variance inflation due to
 multicollinearity. The ridge parameter is selected automatically using the
 approach implemented in the 'ridgregextra' package (Karadag, Sazak, and
 Aydin, 2023) <https://CRAN.R-project.org/package=ridgregextra>, described
 further in Karadag, Sazak, and Aydin (2026)
 <doi:10.1080/02664763.2026.2655681>, which targets a variance inflation
 factor (VIF) close to but not below 1, removing the need for manual tuning.
 Returns comprehensive outputs (coefficients, fitted values, residuals, mean
 squared error (MSE), standard errors, R-squared, and adjusted R-squared)
 through a simple x/y interface.

Fit a Poisson regression to carcass distance data and integrate over the searched area at a wind farm to estimate the fraction of carcasses falling in the searched area and format the output for use as the dwp parameter in the 'GenEst' or 'eoa' package for estimating bird and bat mortality, following Dalthorp, et al. (2024) <doi:10.3133/tm7A3>.

Regression for a discrete response, where the conditional distribution is modelled via a discrete Weibull distribution.

Provides methods for efficient algebraic operations and factorization of dyadic matrices using 'Rcpp' and 'RcppArmadillo'. The details of dyadic matrices and the corresponding methodology are described in Kos, M., Podgórski, K., and Wu, H. (2025) <doi:10.48550/arXiv.2505.08144>.

Provides methods for analyzing categorical dyadic sequences using transition matrices within the Longitudinal Actor-Partner Interdependence Model and Markov-chain framework. The package supports empirical transition counts, maximum likelihood estimation of transition probabilities, and identification of univariate and bivariate patterns of interaction in dyadic sequences.
