1 | TGST(Z, S, phi, method = "nonpar")
|
Z |
A vector of true disease status (No disease / treatment success coded as Z=0, diseased / treatment failure coded as Z=1). |
S |
A vector of risk Score. |
phi |
Percentage of patients taking gold standard test. |
method |
Method for searching for the optimal tripartite rule, options are "nonpar" (default) and "semipar". |
