MetaModelResult

class MetaModelResult(*args)

Data structure containing a metamodel.

Available constructor:

MetaModelResult(model, metaModel, residuals, relativeErrors)

Parameters
modelFunction

Physical model approximated by a metamodel.

metaModelFunction

Definition of the response surface(s) of the model’s output(s).

residualssequence of float

The residual values defined as follows for each output of the model: \displaystyle \frac{\sqrt{\sum_{i=1}^N (y_i - \hat{y_i})^2}}{N} with y_i the N model’s values and \hat{y_i} the metamodel’s values.

relativeErrorssequence of float

The relative errors defined as follows for each output of the model: \displaystyle \frac{\sum_{i=1}^N (y_i - \hat{y_i})^2}{N \Var{\vect{Y}}} with \vect{Y} the vector of the N model’s values y_i and \hat{y_i} the metamodel’s values.

Notes

Structure created by the method run() of KrigingAlgorithm or FunctionalChaosAlgorithm and obtained thanks to the method getResult() of these classes.
