Initializetrialparameter {BayesianPlatformDesignTimeTrend} R Documentation

Initializetrialparameter

Description

This function initialises the inner parameter used in simulate.trial function

Usage

Initializetrialparameter(response.probs, ns)


Arguments

 response.probs A vector of response probability of each arm ns A vector of accumulated number of patient at each stage

Value

A list of initialised parameters including the number of arms for this trial 'K', the number of arm active 'armleft', the index of treatment arm 'treatmentindex', the vector of total number of patients allocated to each arm 'n' the number of total number of patients survived for each arm 'y1', the matrix for true response probability of each arm at each stage 'groupwise.response.probs' which is required for the time trend study, the vector of randomisation probability for each arm 'randomprob', the array of arm assignment for each patient 'z', the array of outcome for each patient 'y', the array of the stage index for each patient 'group_indicator', the matrix of the probability of each arm to be the best at each stage 'post.prob.best.mat'.
