Difference between the Error Rate and Significance Level, Standard Approach
Description
Calculate the difference between the error rate and significance level for the secondary endpoint, standard (original) approach.
Usage
secControl(d, alpha, cvec, gammaVec, ExtrmLoc, type = 2)
Arguments
d |
boundary of secondary endpoint at the final look (a number, d_(K)) |
alpha |
targeted significance level for the secondary endpoint |
cvec |
a vector of calculated primary boundaries |
gammaVec |
square root of information |
ExtrmLoc |
an integer between 1 and K, locate the maximum of type I error of secondary endpoint |
type |
type of sequential procedures. Type 1 OBF d, Type 2 POC d. |
Value
difference between alpha and the calculated error rate.
