outputDriftWithBounds {GroupSeq}R Documentation

console output

Description

This function prints out results from function 'computeAlphaLevel' into the console

Usage

outputDriftWithBounds(n, probTotal, drift, expectedStoppingTime, secondTimeScaleIsUsed, t, t2, t2max, lowerBounds, upperBounds, probStopping, probExceedingUpper, probExceedingLower, confidenceLevel)

Arguments

n is the number of interim analyses.
probTotal is the total type I error used.
drift vector of drift parameters
expectedStoppingTime is expected stopping time (not implemented).
secondTimeScaleIsUsed second time/information scale (yes=>secondTimeScaleIsUsed==TRUE, no=>secondTimeScaleIsUsed==FALSE)
t is the vector of information times.
t2 is the second or information time scale, for covariances
t2max maximum of t2
lowerBounds is the vector of lower standardized boundaries
upperBounds is the vector of upper standardized boundaries
probStopping is the prob of reaching ith analysis and stopping.
probExceedingUpper is the prob of reaching ith and exceeding upper.
probExceedingLower is the prob of reaching ith and exceeding lower.
confidenceLevel desired power respectively confidence level

Note

Note: probTotal, expectedStoppingTime and probStopping are included but not used.
Note: t2 is the information time scale provided that two have been specified.

This function is meant to be called in context of using groupseq

Examples

## a very simple fictious one:
outputDriftWithBounds(1, 0.05, 1.64485, 0.5, FALSE, 1, 0, 0, -8, 1.6449, 0.05, 0.05, 0.05, 00.5)
## with the following result:
