prime_image {eel}R Documentation

Calculating prime-image based on similarity mapping for the mean

Description

The function calculates the prime image of the given point based on the similarity mapping defined in the EEL calculaiton.

Usage

prime_image(theta_tilda, theta, x)
## Default S3 method:
prime_image(theta_tilda,theta,x)

Arguments

theta_tilda

Sample mean or the maximum empirical likelihood estimate of the estimating equaitons.

theta

Value to be evaluated.

x

Data matrix.

Details

The prime image was found by solving the equation

f(\zeta'')=\zeta'.

See the reference paper for details.

Value

The function returns a vector, with the same length as the mean, representing the prime image of the point theta, based on the similarity mapping defind in EEL calculation.
