outputDriftWithBounds: 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

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:
