abstract: Contains functions for fitting shared frailty models with a semi-parametric
  baseline hazard with the Expectation-Maximization algorithm. Supported data formats
  include clustered failures with left truncation and recurrent events in gap-time
  or Andersen-Gill format. Several frailty distributions, such as the the gamma, positive
  stable and the Power Variance Family are supported.
