The Eikos Sensitivy Analysis Toolbox supports “state of the art” sensitivity analysis methods (local as well as global). Sensitivity analysis (SA) is used to assess the influence of model parameters on model predictions.
The Eikos Sensitivity toolbox is an optional fully integrated module for Ecolego and is thus most suitable for use with Ecolego models, although external models are also supported by exporting/importing samples of model inputs and/or model predictions.
Correlations between parameters may be induced by rank order correlation (method of Iman and Conover). The supported sampling techniques are: Monte carlo, Latin Hypercube and Quasi-random LPt. The SA methods included are:
Eikos provides a Graphical User Interface (GUI) which let you:
It is also possible to perform sensitivity analysis on groups of parameters (using extensions of the Sobol or EFAST methods). In this way the influence of each of the selected parameters as well as any combination of them is accounted for when computing the sensitivity indices on a given output.
Ecolego is a powerful and flexible software tool for creating dynamic models and performing deterministic or probabilistic simulations. It can be used for conducting risk assessments of complex dynamic systems evolving over time with any number of species.
The radionuclide toolbox is a plug-in for Ecolego for modelling of radionuclides. The radionuclide toolbox features a database containing all nuclide isotopes and their decay constants and decay energies.
The parameter database toolbox provides a connection between Ecolego and a parameter database.
Over the past four years, an informal working group has developed to investigate existing sensitivity analysis methods, examine new methods, and identify best practices.
We have launched the 8th edition of our modelling tool Ecolego.
