JT.rank.SM {CLAST} | R Documentation |
Calculates the Jennison & Turnbull (1983) ranking of each possible outcome of the sample space generated from a sequential design.
JT.rank.SM(obj)
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. |
a list with element "lims" as well as all elements of argument obj. The extra element contains the JT rank of each possible the 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.

# Component "lims" contains the rank of each sequential binary
# outcome. The same rank is assigned to outcomes with the same
