eff: Efficiency generic function

In OWEA: Optimal Weight Exchange Algorithm for Optimal Designs for Three Models

Efficiency generic function

Description

A generic function that returns the efficiency for either exact designs to approximate designs or exact design to a given design

Usage

eff(exact_design, ex = NULL)

## Default S3 method:
eff(exact_design, ex = NULL)

## S3 method for class 'dropout'
eff(exact_design, ex = NULL)

## S3 method for class 'proportional'
eff(exact_design, ex = NULL)

## S3 method for class 'interference'
eff(exact_design, ex = NULL)

Arguments

exact_design	A S3 object returned by design function.
ex	Matrix. Design to be compared to. Default is NULL.

Value

Numeric. Relative Efficiency. If ex is given, return relative efficiency by Φ_{example}/Φ_{exact\_design}; If ex is missing, return relative efficiency by Φ_{approx\_design}/Φ_{exact\_design}.
