Develop spatial interaction models (SIMs).  SIMs predict the
    amount of interaction, for example number of trips per day, between
    geographic entities representing trip origins and destinations.
    Contains functions for creating origin-destination datasets
    from geographic input datasets and calculating movement between
    origin-destination pairs with constrained, production-constrained,
    and attraction-constrained models (Wilson 1979) <doi:10.1068/a030001>.

Implements outranking-based trace clustering for process
    mining. Pairwise similarity between traces is assessed on multiple,
    problem-specific criteria using ELECTRE-III-style partial concordance
    and discordance indices with indifference, similarity and veto
    thresholds. The aggregated credibility matrix is then clustered using
    normalized spectral clustering or hierarchical clustering. Also
    includes outlier trimming, must-link/cannot-link adjustments,
    validation indices and diagnostic plots.

A lightweight, dependency-free engine to build multi-page PDF
    reports quickly on top of R's built-in graphics device ('pdf'/'cairo_pdf').
    Content is placed by a measured flow layout: every text block reports its
    real width and height via 'strwidth'/'strheight', the vertical cursor
    advances by measured height, and pages break automatically. This eliminates
    the text-overlap of dead-reckoned coordinate reports (such as the 'nmw'
    NONMEM diagnostic reports) and replaces slow '.Rmd'/'knitr'/'LaTeX'
    pipelines for fixed report generation. Interactive AcroForm CRFs are out of
    scope and handled by the sibling 'pdfCRF' package.

Simulates and plots quantities of interest (relative
    hazards, first differences, and hazard ratios) for linear coefficients,
    multiplicative interactions, polynomials, penalised splines, and
    non-proportional hazards, as well as stratified survival curves from Cox
    Proportional Hazard models. It also simulates and plots marginal effects
    for multiplicative interactions. Methods described in Gandrud (2015)
