Sensitivity analysis in Ecolego

For tutorials of how to use the toolbox, please see Sensitivity analysis examples.

Methods

The following methods are included in the Sensitivity analysis toolbox:

Correlation/Regression coefficients:

Pearson - Pearson product-moment correlation coefficient
Spearman - Spearman’s rank correlation coefficient
SRC - Standardized Regression Coefficient
SRRC - Standardized Rank Regression Coefficient
PCC - Partial Correlation Coefficient
PRCC - Partial Rank Correlation Coefficient

* included in standard Ecolego + EASI

Screening methods:

Morris - A computationally inexpensive global screening method
Garten - OAT design to compute customized impact of input factors on model output
Local - OAT design to compute local impact of input factors on model output

Variance-based methods:

Method	Description	First order	Total order	Custom order
Sobol	Brute force method to compute any order of sensitivity indices	OK	OK	OK
FAST	Fourier Amplitude Sensitivity Test	OK
EFAST	Extended Fourier Amplitude Sensitivity Test	OK	OK
EASI	An effective algorithm for computing global sensitivity indices	OK

The toolbox is made up of the following views

Analysis

Two new charts are included with the toolbox.

Correlation time chart - A chart which plots correlation coefficients over time.
Correlation pie chart - A pie chart with correlation coefficients.
