This function calculates the exponential hazard rates for the conditional survival functions
surv.exp.gt.model(pilm, lm, gtprev, GRR, zmodel, interval)A vector of length three containing the exponential hazard rates
Probability that the time-to-event is greater than lm
Landmark time used for powering the study
Relative genotypic frequency
Genotype Hazard Ratio
Genetic Risk Model (choices are "additive", "recessive" or "dominant")
Interval to search for baseline hazard rate
