`lambda` |
Baseline exponential hazard rate |

`p` |
Relative genotype frequency |

`crate` |
Desired censoring rate |

`rootint` |
Interval to be searched for the root |

The time to event distribution *T* is assumed to be a mixture of
exponentials with parameter *λ_0*, *λ_1*
and *λ_2* with mixing proportion
*p_0*,*p_1* and *p_2*.
Suppose that the censoring distribution is uniform on the interval
*[0,b]*.
This function calculates *b* for a desired censoring rate.
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.

This function returns a list from the `uniroot`

function. The
root component of this list in the
