Quant: Quantile function

In coxsei: Fitting a CoxSEI Model

Description

calculates the value of the quantile function (inverse of the distribution function) of the survival variable with given intensity/hazard function.

Usage

Quant(p, int, tolerance = .Machine$double.eps, ...)

Arguments

p	the (probability) values to calculate the quantiles at
int	the intensity/hazard function. Has to be vectorized.
tolerance	tolerated numerical error in inverting the distribution function.
...	arguments to be passed to CumInt (eventually to integrate)

Value

a numerical value or vector giving the values of the quantile function at x
