Tasks
As a first step of a Sensitivity analysis, a model is defined or loaded (using the Model editor). A model is generally defined with a number of input parameters and model outputs where the model outputs are allowed to be time dependent. Different kinds of models are supported by Eikos:
The more general case when output samples can somehow be generated given values of input parameters is also supported (see the section Importing and exporting data).
Each parameter can be assigned one or more of the following (Using the Parameter settings editor):
Depending on the selected Sensitiviy Analysis method, either a PDF, scalar value or minimum/maximum value is required. For most methods, probability distributions are required of the parameters. The exceptions are:
For parameters not included in the analysis, scalar values must be set.
Methods supported are
After defining a model, the model parameters and outputs to be used in the Sensitivity Analysis must be selected in the Parameter selection editor.
Two or more selected parameters can be assigned to a group. 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. The defined groups are only used in the Sobol group indices or EFAST method. For other methods any assigned groups are ignored.
