Description: Count transformation models featuring parameters
        interpretable as discrete hazard ratios, odds ratios,
        reverse-time discrete hazard ratios, or transformed
        expectations. An appropriate data transformation for a count
        outcome and regression coefficients are simultaneously
        estimated by maximising the exact discrete log-likelihood using
        the computational framework provided in package 'mlt',
        technical details are given in Siegfried & Hothorn (2020)
        <DOI:10.1111/2041-210X.13383>. The package also features joint
        count transformation models with covariate-dependent
        correlations applied to a species community of three aquatic
        birds <DOI:10.48550/arXiv.2201.13095>.
