Package: cotram Title: Count Transformation Models Version: 0.6-0 Date: 2025-11-19 Authors@R: c( person(given = "Sandra", family = "Siegfried", role = c("aut", "cre"), email = "sandra.siegfried@alumni.uzh.ch", comment = c(ORCID = "0000-0002-7312-1001")), person(given = "Luisa", family = "Barbanti", role = "aut", comment = c(ORCID = "0000-0001-5352-5802")), person(given = "Torsten", family = "Hothorn", role = "aut", email = "Torsten.Hothorn@R-project.org", comment = c(ORCID = "0000-0001-8301-0471"))) 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) . The package also contains an experimental implementation of multivariate count transformation models with an application to multi-species distribution models .
