Summarizes characteristics of linear mixed effects models without 
    data or a fitted model by converting code for fitting lmer() from 'lme4' 
    and lme() from 'nlme' into tables, equations, and visuals. Outputs can be 
    used to learn how to fit linear mixed effects models in 'R' and to 
    communicate about these models in presentations, manuscripts, and analysis 
    plans.

Calculates cost surfaces based on slope to be used when modelling pathways and movement potential within a landscape (Lewis, 2021) <doi:10.1007/s10816-021-09522-w>.

Construct core collections using the information measure 'Length 
    of Encoded Attribute Values' (LEAV) using qualitative and/or quantitative
    trait data as described by Balakrishnan and Suresh (2001a) 
    <https://indianjournals.com/article/ijpgr-14-1-006> and (2001b) 
    <https://indianjournals.com/article/ijpgr-14-3-005>.

Implements leave-out estimation of variance components in
    two-way fixed effects models as an 'R' translation of the original
    'MATLAB' package of Kline, Saggio, and Solvsten (2020)
    <doi:10.3982/ECTA16410>. The package includes graph-based connected-set
    pruning, leave-out bias correction, leverage computation by exact and
    randomized algorithms, fixed effect estimation helpers, and companion
    model-fit summaries for matched worker-firm panels in the spirit of
    Abowd, Kramarz, and Margolis (1999) <doi:10.1111/1468-0262.00020>.

A set of all-cause and cause-specific life expectancy sensitivity and decomposition methods, including Arriaga (1984) <doi:10.2307/2061029>, others documented by Ponnapalli (2005) <doi:10.4054/DemRes.2005.12.7>, lifetable, numerical, and other analytic or algorithmic approaches such as Horiuchi et al (2008) <doi:10.1353/dem.0.0033>, or Andreev et al (2002) <doi:10.4054/DemRes.2002.7.14>.

Utilities for querying plain text accounting files from 'Ledger', 'HLedger', and 'Beancount'.

An educational package for teaching statistics and mathematics in both primary and higher education. The objective is to assist in the teaching/learning process, both for student study planning and teacher teaching strategies. The leem package aims to provide, in a simple yet in-depth manner, knowledge of statistics and mathematics to anyone who wants to study these areas of knowledge.
