Dataset from simulated regression survival model #2 as described in Dazard et al. (2015). Here, the regression function uses some informative predictors. The rest represent un-informative noisy covariates, which are not part of the design matrix. Survival time was generated from an exponential model with rate parameter \(\lambda\) (and mean 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].
Synthetic.2Each 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.
