exp_factor: Calculating expansion factor for EEL for the mean

Description

The function calculates the first order expansion factor of EEL for the mean.

Usage

exp_factor(x, theta)
"exp_factor"(x,theta)

Arguments

x

Data matrix of interest.

theta

The value to be evaluated.

Value

The function will return a numerical value representing the value of the expansion factor calculated.

Details

The first order expansion factor for calculating EEL is defined as $$\gamma(n,l(\theta))=1+\frac{l(\theta)}{2n}.$$
