EV.Tcomb  R Documentation 
This function computes the expected value of Cuzick & Edwards T_{comb} test statistic in disease clustering, where T_{comb} is a linear combination of some T_k tests.
The argument, n_1, is the number of cases (denoted as n1
as an argument).
The number of cases is denoted as n_1 to match the casecontrol class labeling,
which is just the reverse of the labeling in \insertCitecuzick:1990;textualnnspat.
The argument klist
is the vector
of integers specifying the indices of the T_k values used
in obtaining the T_{comb}.
The argument sig
is the covariance matrix of the vector of T_k values used in Tcomb
, and can be computed
via the the covTcomb
function.
See page 87 of (\insertCitecuzick:1990;textualnnspat) for more details.
