Variable selection in semiparametric transformation models for right-censored data

We study variable selection in general transformation models for right-censored data. The models studied can incorporate external time-varying covariates, and they include the proportional hazards ...

Transformations: Logged variables

Explain what a non-linear transformation is and identify the log transformation as a type of non-linear transformation. Explain what can be achieved with a log transformation and identify situations ...
