OptSig.BootWeight | R Documentation |
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
OptSig.BootWeight(y,x,Rmat,rvec,p=0.5,k=1,nboot=3000,wild=FALSE,Figure=TRUE)
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) |
The bootstrap can be conducted using either iid resampling or wild bootstrap.
alpha.opt |
Optimal level of significance |
crit.opt |
Critical value at the optimal level |
Applicable to a linear regression model
