Estimating the survival curve with survreg()

We can now estimate the survival of the breast cancer patients in the GBSG2 data using a Weibull model.

The Weibull distribution has two parameters, which determine the form of the survival curve.

The survival package and the GBSG2 data are loaded for you in this exercise.

Instructions

  • Estimate a Weibull model for the breast cancer patients.
  • Compute the estimated survival curve from the model using the predict() function with type = "quantile".
  • Create a data.frame with the time points and corresponding survival probabilities.
  • Look at the first few lines of the result using the function head().
