This function calculates the exponential hazard rates for the conditional survival functions

1 | ```
surv.exp.gt.model(pilm, lm, gtprev, GRR, zmodel, interval)
``` |

`pilm` |
Probability that the time-to-event is greater than lm |

`lm` |
Landmark time used for powering the study |

`gtprev` |
Relative genotypic frequency |

`GRR` |
Genotype Hazard Ratio |

`zmodel` |
Genetic Risk Model (choices are "additive", "recessive" or "dominant") |

`interval` |
Interval to search for baseline hazard rate |

Determines the time to event distributions in the three component mixture model discussed in the reference below. It is not intended to be called directly by the user. To conduct power calculations, use sim.snp.expsurv.power or the convenience wrapper function survSNP.power.table.

A vector of length three containing the exponential hazard rates
