%description
Allows for the specification of deep conditional transformation models
(DCTMs) and ordinal neural network transformation models, as described in
Baumann et al (2021) <doi:10.1007/978-3-030-86523-8_1> and Kook et al
(2022) <doi:10.1016/j.patcog.2021.108263>. Extensions such as
autoregressive DCTMs (Ruegamer et al, 2022,
<doi:10.48550/arXiv.2110.08248>) and transformation ensembles (Kook et al,
2022, <doi:10.48550/arXiv.2205.12729>) are implemented.
