Let [ Mn(C) ] denote the set of linear maps from the n × n complex matrices into themselves and let $\hat\Omega_n$ denote the set of complex doubly stochastic matrices, i.e. complex matrices whose row ...

The traditional linear transformation model assumes a linear relationship between the transformed response and the covariates. However, in real data, this linear relationship may be violated. We ...

This is a zip containing the codes and data for the 'Simulation Studies' and 'Real data application' sections in the paper 'Deep Partially Linear Transformation Model for Right-Censored Survival Data' ...
