evalTwoPhase: evalTwoPhase functions

In yaqicao/TwoPhaseAccuracy: Two-phase stratified sampling and analysis for predicting binary outcomes

Description

evalTwoPhase functions

Usage

evalTwoPhase(Outcome, X, Z, Stratum, Phase_ID, namesX, namesZ, q, p, method)

Arguments

Outcome	vector of length n
X	matrix of size n x t (t standard predictors included in the model)
Z	matrix of size n x m (m biomarkers included in the model); some subjects have NA values
Stratum	vector of length n
Phase_ID	vector of length n
namesX	names of X; vector of length t
namesZ	names of Z; vector of length m
q	threshold value for TPR(q)
p	threshold value for FPR(p)
method	"Benchmark", "ML"
numBoot	number of bootstrap samples

Value

calculate TPR, FPR, and AUC, with two-phase estimators implemented via function tps() in R package "osDesign" (Haneuse and others, 2011).

Examples

est_benchmark <- evalTwoPhase(Outcome, X, Z, Stratum, Phase_ID, namesX, namesZ, q=0.2, p=0.2, method="Benchmark")
