1.2 Enhancements

• Added ability specify initial parameter values for models using the “inits” argument
• Added functionality for passing arguments to stats::optim() for select models
  • Available for built-in 3-parameter Weibull and models dependent on flexsurv including: 2-parameter Weibull, log-logistic, Gompertz, lognormal, 2-parameter gamma, generalized gamma models
• Added “shift” argument to fc_pred()
  • The user can obtain survival function predictions with start time for a survival model shifted forward in time

1.2 Bug fixes
