Building on top of the 'RcppArmadillo' linear
    algebra functionalities to do fast spatial interaction models in the
    context of urban analytics, geography, transport modelling. It uses
    the Newton root search algorithm to determine the optimal cost
    exponent and can run country level models with thousands of origins
    and destinations. It aims at implementing an easy approach based on
    matrices, that can originate from various routing and processing steps earlier in an workflow. 
    Currently, the simplest form of production, destination and
    doubly constrained models are implemented.

Implementation of the Control Polygon Reduction and Control Net
    Reduction methods for finding parsimonious B-spline regression models.

Implements the three-step workflow for robust analysis of change in 
    two repeated measurements of continuous outcomes, described in Ning et al.

    a continuous outcome", BMC Medical Research Methodology.

The primary function makeCPMSampler() generates a sampler function which performs the correlated pseudo-marginal method of Deligiannidis, Doucet and Pitt (2017) <arXiv:1511.04992>. If the 'rho=' argument of makeCPMSampler() is set to 0, then the generated sampler function performs the original pseudo-marginal method of Andrieu and Roberts (2009) <DOI:10.1214/07-AOS574>. The sampler function is constructed with the user's choice of prior, parameter proposal distribution, and the likelihood approximation scheme. Note that this algorithm is not automatically tuned--each one of these arguments must be carefully chosen.
