Description

The function calculates the first order expansion factor of EEL for the parameters defined by estimating equations.

Usage

1
2
3
exp_factor_est(x, theta, equation)
## Default S3 method:
exp_factor_est(x,theta,equation)

Arguments

x

Data Matrix.

theta

The value to be evaluated.

equation

The estimating equation by which the parameters are defined.

Details

The first order expansion factor for calculating EEL is defined as

r(n,l(theta))=1+l(theta)/2n.

The estimating equation input has to be a function of theta.

Value

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