Detects, describes, and analyzes drought events from time series
    of drought indices, such as the Standardized Precipitation-Evapotranspiration
    Index (SPEI). Identifies drought episodes based on threshold values and calculates 
    their duration, intensity, severity, and peak month. Includes utilities for summarizing
    and visualizing drought dynamics over time. The Standardized Precipitation-Evapotranspiration
    Index is described in Vicente-Serrano et al. (2010) 
    <doi:10.1175/2009JCLI2909.1>.

Estimation of the total population size from capture-recapture data efficiently and with low bias implementing the methods from Das M, Kennedy EH, and Jewell NP (2021) <arXiv:2104.14091>. The estimator is doubly robust against errors in the estimation of the intermediate nuisance parameters. Users can choose from the flexible estimation models provided in the package, or use any other preferred model.

Implementation of the Density Ratio Permutation Test for testing the goodness-of-fit of a hypothesised ratio of two densities, as described in Bordino and Berrett (2025) <doi:10.48550/arXiv.2505.24529>.

Several quality measurements for investigating the performance of dimensionality reduction methods are provided here. In addition a new quality measurement called Gabriel classification error is made accessible, which was published in Thrun, M. C., Märte, J., & Stier, Q: "Analyzing Quality Measurements for Dimensionality Reduction" (2023), Machine Learning and Knowledge Extraction (MAKE), <DOI:10.3390/make5030056>.

An Implementation of Dimensionality Reduction
    via Regression using Kernel Ridge Regression.

The doubly regularized matrix-variate regression solves a low-rank-plus-sparse
    structure for matrix-variate generalized linear models through a weighted
    combination of nuclear-norm and L1-norm.
    The methodology implemented by this package is described in the paper "Doubly
    Regularized Matrix-Variate Regression", which has been tentatively accepted for
    publication but does not yet have a DOI or URL. A formal citation will be added
    in a future update once the final publication details are available.
