outputDriftWithBounds {GroupSeq} | R Documentation |
This function prints out results from function 'computeAlphaLevel' into the console
outputDriftWithBounds(n, probTotal, drift, expectedStoppingTime, secondTimeScaleIsUsed, t, t2, t2max, lowerBounds, upperBounds, probStopping, probExceedingUpper, probExceedingLower, confidenceLevel)
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: 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

## 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: ############################ # # # Output Drift with Bounds # # # ############################ # # #*-----* #*Drift: 1.6448 #*-----* #Maximum Information: 0 #Power is 0.5 # # # Times Lower Bounds Upper Bounds exit Prob cumulative Exit Prob #1 1 -8 1.6449 0.1 0.1
