Efficiency of the system

Description

The efficiency of a system expressed in terms of the deviation from linear scalability.

Usage

## S4 method for signature 'USL'
efficiency(object)

Arguments

object

A USL object.

Details

The function returns a vector which contains the deviation from linearity for every measurement of the model input. A value of 1 indicates linear scalability while values less than 1 correspond to the fraction of the measurement compared to linear scalability.

Value

A vector of numeric values.
