a function
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)
f <- grab_GFUN(create_GFUN(mybasis))
# Evaluate GFUN at mean and variance: should be close to zero
n <- nrow(geexex)
f(c(mean(geexex$Y1), var(geexex$Y1) * (n - 1)/n))
