Synthetic.1: Synthetic Dataset #1: $p < n$ case
Description
Modeling survival model #1 as described in Dazard et al. (2015) with censoring.
Here, the regression function uses all of the predictors, which are also part of the design matrix.
Survival time was generated from an exponential model with rate parameter $\lambda$ (and mean $\frac{1}{\lambda}$)
according to a Cox-PH model with hazard exp(eta), where eta(.) is the regression function.
Censoring indicator were generated from a uniform distribution on [0, 3].
In this synthetic example, all covariates are continuous, i.i.d. from a multivariate uniform distribution on [0, 1].format
Each dataset consists of a numeric matrix containing $n=250$ observations (samples)
by rows and $p=3$ variables by columns, not including the censoring indicator and (censored) time-to-event variables.
It comes as a compressed Rda data file.source
