Opt.SigBootWeight: Weighted Optimal Significance Level for the F-test based on the bootstrap

Description

The function calculates the weighted optimal level of significance for the F-test

The weights are obtained from the bootstrap distribution of the non-centrality parameter estimates

Usage

Opt.SigBootWeight(y,x,Rmat,rvec,p=0.5,k=1,nboot=3000,wild=FALSE,Figure=TRUE)

Arguments

y

a matrix of dependent variable, T by 1

x

a matrix of K independent variable, T by K

Rmat

a matrix for J restrictions, J by (K+1)

rvec

a vector for restrictions, J by 1

p

prior probability for H0, default is p = 0.5

k

relative loss from Type I and II errors, k = L2/L1, default is k = 1

nboot

the number of bootstrap iterations, the default is 3000

wild

if TRUE, wild bootsrap is conducted (default); if FALSE, bootstrap is based on iid resampling

Figure

show graph if TRUE . No graph if FALSE (default)

Value

alpha.opt

Optimal level of significance

crit.opt

Critical value at the optimal level

Details

The bootstrap can be conducted using either iid resampling or wild bootstrap.
