coverage: 95% empirical coverage probability for a pqrBayes object

In pqrBayes: Bayesian Penalized Quantile Regression

95% empirical coverage probability for a pqrBayes object

Description

Calculate 95% empirical coverage probabilities for regression coefficients under linear, binary LASSO, group LASSO and VC models, respectively.

Usage

coverage(object,coefficient,u.grid=NULL,model="linear")

Arguments

object	the pqrBayes object.
coefficient	the vector of true regression coefficients under a linear model (i.e., LASSO), binary LASSO, group LASSO, or the matrix of true varying coefficients evaluated on the grid points under a varying coefficient model.
u.grid	the vector of grid points under a varying coefficient model. When assessing empirical coverage probabilities under a linear model (i.e., LASSO), binary LASSO or group LASSO, u.grid = NULL.
model	the model to be fitted. Users can also choose "linear" for a linear model (i.e., LASSO), "binary" for binary LASSO, "group" for group LASSO, and "VC" for a varying coefficient model.
