Includes an interactive application designed to support
    educators in wide-ranging disciplines, with a particular focus on
    those teaching introductory statistical methods (descriptive and/or
    inferential) for data analysis. Users are able to randomly generate
    data, make new versions of existing data through common adjustments
    (e.g., add random normal noise and perform transformations), and check
    the suitability of the resulting data for statistical analyses.

Computes confidence intervals for variance using the Chi-Square distribution, without requiring raw data. Wikipedia (2025) <https://en.wikipedia.org/wiki/Chi-squared_distribution>. 'All-in-One Chi Distribution CI' provides functions to calculate confidence intervals for the population variance based on a chi-squared distribution, utilizing a sample variance and sample size. It offers only a simple all-in-one method for quick calculations to find the CI for Chi Distribution.

Provides an implementation of simultaneous tolerance bounds (STB), useful for checking whether a numeric vector fits to a hypothetical null-distribution or not.
             Furthermore, there are functions for computing STB (bands, intervals) for random variates of linear mixed models fitted with package 'VCA'. All kinds of, possibly transformed 
             (studentized, standardized, Pearson-type transformed) random variates (residuals, random effects), can be assessed employing STB-methodology.

A set of consistent, opinionated functions to quickly check
    function arguments, coerce them to the desired configuration, or
    deliver informative error messages when that is not possible.

Provides functions to model and forecast crop yields using a spatial temporal conditional copula approach. 
    The package incorporates extreme weather covariates and Bayesian Structural Time Series models to analyze crop 
    yield dependencies across multiple regions. Includes tools for fitting, simulating, and visualizing results. 
    This method build upon established R packages, including 'Hofert' 'et' 'al'. (2025) <doi:10.32614/CRAN.package.copula>, 
    'Scott' (2024) <doi:10.32614/CRAN.package.bsts>, and 'Stephenson' 'et' 'al'. (2024) <doi:10.32614/CRAN.package.evd>.
