print.summary.HessMLP: Print method of the summary HessMLP Class

In NeuralSens: Sensitivity Analysis of Neural Networks

Print method of the summary HessMLP Class

Description

Print the sensitivity metrics of a HessMLP object. This metrics are the mean sensitivity, the standard deviation of sensitivities and the mean of sensitivities square

Usage

## S3 method for class 'summary.HessMLP'
print(x, round_digits = NULL, ...)

Arguments

x	summary.HessMLP object created by summary method of HessMLP object
round_digits	integer number of decimal places, default NULL
...	additional parameters

Examples

## Load data -------------------------------------------------------------------
data("DAILY_DEMAND_TR")
fdata <- DAILY_DEMAND_TR

## Parameters of the NNET ------------------------------------------------------
hidden_neurons <- 5
iters <- 250
decay <- 0.1
