correct_by: Correct sandwich components

Description

Modifies the matrices in a sandwich_components object using the function and options in a correct_control object. The function correction is a utility for creating correct_control objects.

Usage

correct_by(.components, .correct_control)

Value

the result of .FUN in .correct_control.

Arguments

.components

an object of class sandwich_components

.correct_control

an object of class correct_control

Details

See the finite sample corrections vignette for further examples.

Examples

myee <- function(data){
   function(theta){
    c(data$Y1 - theta[1],
     (data$Y1 - theta[1])^2 - theta[2])
   }
 }
mybasis <- create_basis(
   estFUN = myee,
   data   = geexex)
mats <- estimate_sandwich_matrices(mybasis, .theta = c(5.04, 10.04))
correct_by(mats,
   .correct_control =  correction(fay_bias_correction, b = .75))
