LR.stats.SM {CLAST} | R Documentation |
Calculates all possible LR based limits for p from an object that contains all possible data sets from a group sequential trial.
LR.stats.SM(obj, alpha = 0.05, type = "upper")
obj |
a list with elements S, M and design, containing all possible values of total successes S and stopping stage M based on the given design. Typically this is the output of function sample.space or sample.space.2 and will also have elements Y and decision. |
alpha |
nominal coverage error of approximate LR based limits |
type |
character, either "upper" or "lower" |
a list with element "lims" as well as all elements of argument obj. The extra element contains the LR exact limit for each possible outcome.

# Y contains the 364 possible sequential binary outcomes;
# M contains how many stages before the decision;
# S contains the total number of success that produces the decision;
# decision the final binary test result of H0 or H1.
