Perform spatial temporal analysis of moving polygons; a
    longstanding analysis problem in Geographic Information Systems. Facilitates
    directional analysis, distance analysis, and some other simple functionality for
    examining spatial-temporal patterns of moving polygons.

Fits semiparametric linear and multilevel models with non-parametric additive Bayesian additive regression tree (BART; Chipman, George, and McCulloch (2010) <doi:10.1214/09-AOAS285>) components and Stan (Stan Development Team (2021) <https://mc-stan.org/>) sampled parametric ones. Multilevel models can be expressed using 'lme4' syntax (Bates, Maechler, Bolker, and Walker (2015) <doi:10.18637/jss.v067.i01>).

Provides functions for the analysis of
        occupational and environmental data with non-detects. Maximum
        likelihood (ML) methods for censored log-normal data and
        non-parametric methods based on the product limit estimate (PLE)
        for left censored data are used to calculate all of the
        statistics recommended by the American Industrial Hygiene
        Association (AIHA) for the complete data case. Functions for
        the analysis of complete samples using exact methods are also
        provided for the lognormal model. Revised from 2007-11-05
        'survfit~1'.

Tools which allow regression variables to be placed on similar
    scales, offering computational benefits as well as easing interpretation of
    regression output.

Provides standard load profiles (SLPs) for electricity and gas
  published by the German Association of Energy and Water Industries (BDEW
  Bundesverband der Energie- und Wasserwirtschaft e.V.) in a tidy format. The
  electricity profiles cover the 1999 profiles — households (H0), commercial
  (G0–G6), and agriculture (L0–L2) — and the updated 2025 profiles (H25, G25,
  L25, P25, S25), which additionally represent households with photovoltaic
  systems and battery storage. An interface generates an electricity load
  profile over a user-defined date range. A second interface generates daily
  standard load profiles for gas using the synthetic 'SigLinDe' method. More
  information on the data and methodology for electricity is described in
  "Standardlastprofile Strom",
  <https://www.bdew.de/energie/standardlastprofile-strom/>, and for gas in
  "Standardlastprofile Gas",
