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

In NeuralSens: Sensitivity Analysis of Neural Networks

Print method of the summary SensMLP Class

Description

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

Usage

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

Arguments

x	summary.SensMLP object created by summary method of SensMLP object
round_digits	integer number of decimal places, default NULL
boot.alpha	float significance level to show statistical metrics. If NULL, boot.alpha inherits from x is used. Defaults to NULL.
...	additional parameters
