Dynamic regression for time series using Extreme Gradient Boosting with hyper-parameter tuning via Bayesian Optimization or Random Search.

A collection of Japanese text processing tools for filling
    Japanese iteration marks, Japanese character type conversions,
    segmentation by phrase, and text normalization which is based on rules
    for the 'Sudachi' morphological analyzer and the 'NEologd' (Neologism
    dictionary for 'MeCab').  These features are specific to Japanese and
    are not implemented in 'ICU' (International Components for Unicode).

Functions for analysis of data generated from experiments in
    augmented randomised complete block design according to Federer, W.T.
    (1961) <doi:10.2307/2527837>. Computes analysis of variance, adjusted
    means, descriptive statistics, genetic variability statistics etc.
    Further includes data visualization and report generation functions.

Implementation of the augmented
            Simulation-Extrapolation (SIMEX) algorithm proposed by Yi et al. (2015) <doi:10.1080/01621459.2014.922777>
            for analyzing the data with mixed measurement error and misclassification. The main
            function provides a similar summary output as that of glm() function. Both parametric and
            empirical SIMEX are considered in the package.

Extract and process bird sightings records from
    eBird (<http://ebird.org>), an online tool for recording bird
    observations.  Public access to the full eBird database is via the
    eBird Basic Dataset (EBD; see <http://ebird.org/ebird/data/download>
    for access), a downloadable text file. This package is an interface to
    AWK for extracting data from the EBD based on taxonomic, spatial, or
    temporal filters, to produce a manageable file size that can be
    imported into R.

Efficient algorithms
 <https://jmlr.org/papers/v24/21-0751.html>
 for computing Area Under Minimum,
 directional derivatives, and
 line search optimization of a linear model,
 with objective defined as either
 max Area Under the Curve or
 min Area Under Minimum.
