Implementation of uniformly most powerful invariant equivalence
    tests for one- and two-sample problems (paired and unpaired) as described 
    in Wellek (2010, ISBN:978-1-4398-0818-4). Also one-sided alternatives 
    (non-inferiority and non-superiority tests) are supported. Basically a variant 
    of a t-test with (relaxed) null and alternative hypotheses exchanged.

Multivariate modeling of data after deflation of interfering effects. EF Mosleth et al. (2021) <doi:10.1038/s41598-021-82388-w> and EF Mosleth et al. (2020) <doi:10.1016/B978-0-12-409547-2.14882-6>.

Provides a consistent representation of year-based time scales as a
    numeric vector with an associated 'era'. There are built-in era definitions
    for many year numbering systems used in contemporary and historic calendars 
    (e.g. Common Era, Islamic 'Hijri' years); year-based time scales used in 
    archaeology, astronomy, geology, and other palaeosciences (e.g. 
    Before Present, SI-prefixed 'annus'); and support for arbitrary user-defined
    eras. Years can converted from any one era to another using a generalised 
    transformation function. Methods are also provided for robust casting and 
    coercion between years and other numeric types, type-stable arithmetic with 
    years, and pretty-printing in tables.

Automated compound deconvolution, alignment across samples, and identification of metabolites by spectral library matching in Gas Chromatography - Mass spectrometry (GC-MS) untargeted metabolomics. Outputs a table with compound names, matching scores and the integrated area of the compound for each sample. Package implementation is described in Domingo-Almenara et al. (2016) <doi:10.1021/acs.analchem.6b02927>.

Estimation of unknown historical or archaeological dates subject to relationships with other relative dates and absolute constraints, derived as marginal densities from the full joint conditional, using a two-stage Gibbs sampler with consistent batch means to assess convergence. Features reporting on Monte Carlo standard errors, as well as tools for rule-based estimation of dates of production and use of artifact types, aligning and checking relative sequences, and evaluating the impact of the omission of relative/absolute events upon one another.
