ISS (version 1.0.0)

get_p_classification: get_p_classification

Description

Calculate the p-value in Definition 21 of MRCS2023;textualISS.

Usage

get_p_classification(X, y, x0, tau)

Value

A single numeric value in (0, 1].

Arguments

X

a numeric matrix specifying the covariates.

y

a numeric vector with length(y) == nrow(X) and all((y >= 0) & (y <= 1)) specifying the responses.

x0

a numeric vector specifying the point of interest, such that length(x0) == ncol(X).

tau

a single numeric value in [0,1) specifying the threshold of interest.
