This function is called by
sim.survdata and is not intended to be used by itself.
censor.x(x, censor = 0.1)
A matrix or data frame containing covariates
The proportion of observations to designate as being right-censored
The purpose of this function is to efficiently generate indicators for whether or not an observation in simulated duration data is right-censored. In this case, whether or not an observation is right-censored depends on the covariates in the data.
This function randomly draws new coefficients, one for every column of
x, from the normal distribution with mean 0 and
standard deviation of 0.1. It uses these new coefficients to build a linear predictor, to which is added a disturbance term which
is also drawn from N(0,.1). A fixed proportion, given by
censor, of the observations with the highest values of this linear
predictor are set to be
TRUE and the others are set to
A vector of logical values
