dropout: Prostate Cancer Data: Part 2 - a simulated example of study...

Description Format Source References

Description

A simulated data set used in Kim et al. (2016) to illustrate the JPLM method. This data set was generated under settings mimicking the prostate cancer study. For detailed data generation settings, see Kim et al. (2016).

Format

A data frame with 100 observations (n = 100 patients) on the following 4 variables.

ID2

a numeric vector of patient ID.

Status

a numeric (binary) vector indicating whether the study drop-out time (end of follow-up) was informative.

DropTime

a numeric vector of the end of follow-up.

logPSA.base2

a numeric vector of log(baseline PSA + 0.1).

Source

The prostate cancer data have been previously studied by Proust-Lima et al. (2008) and Taylor et al. (2013), among others.
