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.

Data on standard load profiles from the German Association of 
  Energy and Water Industries (BDEW Bundesverband der Energie- und 
  Wasserwirtschaft e.V.) in a tidy format. The data and methodology are 
  described in VDEW (1999), "Repräsentative VDEW-Lastprofile", 
  <https://www.bdew.de/media/documents/1999_Repraesentative-VDEW-Lastprofile.pdf>.
  The package also offers an interface for generating a standard load profile 
  over a user-defined period. For the algorithm, see VDEW (2000), 
  "Anwendung der Repräsentativen VDEW-Lastprofile step-by-step",
  <https://www.bdew.de/media/documents/2000131_Anwendung-repraesentativen_Lastprofile-Step-by-step.pdf>.
