test_boot: Conducting Score Tests for Interaction Using Bootstrap Test

In IrisTeng/CVEK: Cross-Validated Kernel Ensemble

Description

Conduct score tests comparing a fitted model and a more general alternative model using bootstrap test.

Usage

test_boot(n, Y, X12, beta0, alpha0, K_gpr, sigma2_hat, tau_hat, B)

Arguments

n	(integer) A numeric number specifying the number of observations.
Y	(vector of length n) Reponses of the dataframe.
X12	(dataframe, n*(p1\*p2)) The interaction items of first and second types of factors in the dataframe.
beta0	(numeric) Estimated bias of the model.
alpha0	(vector of length n) Estimated coefficients of the estimated ensemble kernel matrix.
K_gpr	(matrix, n*n) Estimated ensemble kernel matrix.
sigma2_hat	(numeric) The estimated noise of the fixed effects.
tau_hat	(numeric) The estimated noise of the random effects.
B	(integer) A numeric value indicating times of resampling when test = "boot".

Details

Bootstrap Test

When it comes to small sample size, we can use bootstrap test instead, which can give valid tests with moderate sample sizes and requires similar computational effort to a permutation test.

Value

pvalue

(numeric) p-value of the test.
