prob_eff_quantile: Quantile of the efficacy rate at each dose.

In escalation: A Modular Approach to Dose-Finding Clinical Trials

Quantile of the efficacy rate at each dose.

Description

Get the estimated quantile of the efficacy rate at each dose under investigation. This is a set of modelled statistics. The underlying models estimate efficacy probabilities in different ways. If no model-based estimate of the median is available, this function will return a vector of NAs.

Usage

prob_eff_quantile(x, p, ...)

Arguments

x	Object of class selector
p	quantile probability, decimal value between 0 and 1
...	arguments passed to other methods

Value

a numerical vector
