Computes the coverage correlation coefficient introduced in <doi:10.48550/arXiv.2508.06402> , a statistical measure that quantifies dependence between two random vectors by computing the union volume of data-centered hypercubes in a uniform space.

Several nonparametric estimators of autocovariance functions. Procedures for constructing their confidence regions by using bootstrap techniques. Methods to correct autocovariance estimators and several tools for analysing and comparing them. Supplementary functions, including kernel computations and discrete cosine Fourier transforms. For more details see Bilchouris and Olenko (2025) <doi:10.17713/ajs.v54i1.1975>.

A comprehensive toolkit for political linguistics featuring a museum
    of famous digital gaffes, phonetic transformation algorithms (Soundex, consonant
    shifts), QWERTY keyboard geometry for typo simulation, syllable parsing, word
    blending (portmanteau creation), and text corruption analysis. Originally
    inspired by the infamous "covfefe" tweet of 2017.

Direct sparse covariance matrix estimation via the covariance graphical lasso by Bien, Tibshirani (2011) <doi:10.1093/biomet/asr054> using the fast coordinate descent algorithm of Wang (2014) <doi:10.1007/s11222-013-9385-5>.

Provides a daily summary of COVID-19 cases, deaths, recovered, tests,
  vaccinations, and hospitalizations for 230+ countries, 760+ regions, 
  and 12000+ administrative divisions of lower level. 
  Includes policy measures, mobility data, and geospatial identifiers.
  Data source: COVID-19 Data Hub <https://covid19datahub.io>.

Load and analyze updated time series worldwide data of reported cases for the Novel Coronavirus Disease (COVID-19) from different sources, including the Johns Hopkins University Center for Systems Science and Engineering (JHU CSSE) data repository <https://github.com/CSSEGISandData/COVID-19>, "Our World in Data" <https://github.com/owid/> among several others. The datasets reporting the COVID-19 cases are available in two main modalities, as a time series sequences and aggregated data for the last day with greater spatial resolution. Several analysis, visualization and modelling functions are available in the package that will allow the user to compute and visualize total number of cases, total number of changes and growth rate globally or for an specific geographical location, while at the same time generating models using these trends; generate interactive visualizations and generate Susceptible-Infected-Recovered (SIR) model for the disease spread.
