Implements the method of successive dichotomizations by
    Bradley and Massof (2018) <doi:10.1371/journal.pone.0206106>, 
    which estimates item measures, person measures and ordered rating
    category thresholds given ordinal rating scale data.

Implements an MCMC sampler for the posterior distribution of arbitrary time-homogeneous multivariate stochastic differential equation (SDE) models with possibly latent components.  The package provides a simple entry point to integrate user-defined models directly with the sampler's C++ code, and parallelizes large portions of the calculations when compiled with 'OpenMP'.

Characterization of a mid-summer drought (MSD) with precipitation
    based statistics. The MSD is a phenomenon of decreased rainfall during a 
    typical rainy season. It is a feature of rainfall in much of Central America
    and is also found in other locations, typically those with a Mediterranean 
    climate. Details on the metrics are in Maurer et al. (2022) 
    <doi:10.5194/hess-26-1425-2022>.
