mean_prob_eff {escalation}

Mean efficacy rate at each dose.

Description

Get the estimated mean 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 mean is available, this function will return a vector of NAs.

Usage

mean_prob_eff(x, ...)

Arguments

x

Object of class selector

Value

a numerical vector
