OneParLogNormalPrior-class: 'OneParLogNormalPrior'

In crmPack: Object-Oriented Implementation of Dose Escalation Designs

OneParLogNormalPrior

Description

OneParLogNormalPrior is the class for a standard CRM with a normal prior on the log power parameter for the skeleton prior probabilities.

Usage

OneParLogNormalPrior(skel_probs, dose_grid, sigma2)

.DefaultOneParLogNormalPrior()

Arguments

skel_probs	(numeric) skeleton prior probabilities. This is a vector of unique and sorted probability values between 0 and 1.
dose_grid	(numeric) dose grid. It must be must be a sorted vector of the same length as skel_probs.
sigma2	(number) prior variance of log power parameter alpha.

Value

an instance of the OneParLogNormalPrior class

Slots
