qcond_gamma: Conditional quantile function for gamma distribution
Description
Conditional quantile function for gamma distribution
Usage
qcond_gamma(rnd, shape, rate, lower_bound, s_obs)
Value
Estimate(s) from the conditional gamma distribution based on given parameters
Arguments
rnd
Vector of quantiles
shape
The shape parameter
rate
The rate parameter
lower_bound
The lower bound to be used (current time)
s_obs
is the survival observed up to lower_bound time,
normally defined from time 0 as 1 - pgamma(q = lower_bound, rate, shape) but may be different if parametrization has changed previously
