Recursive partitioning based on psychometric models,
  employing the general MOB algorithm (from package partykit) to obtain
  Bradley-Terry trees, Rasch trees, rating scale and partial credit trees, and
  MPT trees, trees for 1PL, 2PL, 3PL and 4PL models and generalized partial 
  credit models.

Helper functions for producing reports in Psychology (Reproducible Research). Provides required formatted strings (APA style) for use in 'Knitr'/'Latex' integration within *.Rnw files.

Implementation of 'PsychroLib'
    <https://github.com/psychrometrics/psychrolib> library which contains
    functions to enable the calculation properties of moist and dry air in both
    metric (SI) and imperial (IP) systems of units. References: Meyer, D. and
    Thevenard, D (2019) <doi:10.21105/joss.01137>.

Support functions,  data sets, and vignettes for the 'psych' package. Contains several of the biggest data sets for the 'psych' package as well as four vignettes. A few helper functions for file manipulation are included as well. For more information, see the <https://personality-project.org/r/> web page.

An integrative toolbox of word embedding research that provides:
    (1) a collection of 'pre-trained' static word vectors in the '.RData'
    compressed format <https://psychbruce.github.io/WordVector_RData.pdf>;
    (2) a group of functions to process, analyze, and visualize word vectors;
    (3) a range of tests to examine conceptual associations, including
    the Word Embedding Association Test <doi:10.1126/science.aal4230>
    and the Relative Norm Distance <doi:10.1073/pnas.1720347115>,
    with permutation test of significance; and
    (4) a set of training methods to locally train (static) word vectors
    from text corpora, including 'Word2Vec' <doi:10.48550/arXiv.1301.3781>,
    'GloVe' <doi:10.3115/v1/D14-1162>, and 'FastText' <doi:10.48550/arXiv.1607.04606>.

Person fit statistics based on Quality Control measures are provided for questionnaires and tests given a specified IRT model. Statistics based on Cumulative Sum (CUSUM) charts are provided. Options are given for banks with polytomous and dichotomous data.
