Semiparametric analysis for linear transformation model, such as the proportional hazards model and the proportional odds model, is fitted based on a unified method proposed in Chen(2002) for right censored survival data.
The main function TransModel gives estimates for coefficients and covariance matrix for the predictors in the linear transformation model. Print and summary method can be applied to the returned object.
