Dataset from simulated regression survival model #4 as described in Dazard et al. (2015).
Here, the regression function uses 1/10 of informative predictors in a *p > n* situation with *p = 1000* and *n = 100*.
The rest represents non-informative noisy covariates, which are not part of the design matrix.
Survival time was generated from an exponential model with rate parameter *λ* (and mean *\frac{1}{λ}*)
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, 2].
In this synthetic example, all covariates are continuous, i.i.d. from a multivariate standard normal distribution.

Each dataset consists of a `numeric`

`matrix`

containing *n=100* observations (samples)
by rows and *p=1000* variables by columns, not including the censoring indicator and (censored) time-to-event variables.
It comes as a compressed Rda data file.
