funsExpTrun: Expected Value for Cuzick and Edwards T_{run} Test statistic

Description Usage Arguments Value Author(s) References See Also Examples

Description

Two functions: EV.Trun and EV.Trun.alt.

Both functions compute the expected value of Cuzick and Edwards T_{run} test statistic based on the number of consecutive cases from the cases in the data under RL or CSR independence.

The number of cases are denoted as n_1 (denoted as n1 as an argument) and number of controls as n_0 for both functions (denoted as n0 as an argument), to match the case-control class labeling, which is just the reverse of the labeling in \insertCitecuzick:1990;textualnnspat.

The function EV.Trun.alt uses a loop and takes slightly longer than the function EV.Trun, hence EV.Trun is used in other functions.
