dag_test_ISS {ISS}

dag_test_ISS

Description

Implements the DAG testing procedure given in Algorithm 1 by Müller et al. (2023).

Usage

dag_test_ISS(X0, p, alpha)

Arguments

X0

a numeric matrix giving points corresponding to hypotheses.

p

a numeric vector taking values in (0, 1] such that length(p) == nrow(X0).

alpha

a numeric value in (0, 1] specifying the Type I error rate.

Value

A boolean vector of the same length as p with each element being TRUE if the corresponding hypothesis is rejected and FALSE otherwise.
