Elementary effects method
The elementary effects (EE) method is the most used screening method in sensitivity analysis. EE is applied to identify non-influential inputs for a computationally costly mathematical model or for a model with a large number of inputs, where the costs of estimating other sensitivity analysis measures such as the variance-based measures is not affordable. Like all screening, the EE method provides qualitative sensitivity analysis measures, i.e. measures which allow the identifi… WebElementary effects is a popular choice for sensitivity analysis in the environmental and biological sciences, but the current formulation is not suitable for most real-life models. Furthermore, it is not clear which of the commonly used trajectory generation methods is best. Traditional EE • Effect for input , output : 𝑛=
