funsExpTrun | R Documentation |
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.
See also (\insertCitecuzick:1990;textualnnspat).
