spotPredictMlegp: Meta Model Interface: Maximum Likelihood Estimation for...

Description Usage Arguments Value See Also


Kriging model based on mlegp package. This function uses two settings, which are stored in the spotConfig parameter:
spotConfig$seq.mlegp.constantMean Use constant mean (mu) in mlegp (=1) or linear model (=0); 1 by default
spotConfig$seq.mlegp.min.nugget minimum value of nugget term; 0 by default

If those settings are not in spotConfig their mentioned defaults will be used.

If the numeric value of spotConfig$mlegp.reduce is smaller than the observations in mergedB, spotConfig$mlegp.reduce will specify how many samples should be drawn without replacement from mergedB. This can prevent explosion of time consumption in this function. Mlegp can be used both for single and multi objective SPOT.


spotPredictMlegp(rawB, mergedB, design, spotConfig, fit = NULL)



matrix of raw x and y values


matrix of merged x and y values, does not have replicate entries


design points to be evaluated by the meta model


the list of all parameters is given.


if an existing model fit is supplied, the model will not be build based on data, but only evaluated with the model fit (on the design data). To build the model, this parameter has to be NULL. If it is not NULL the parameters mergedB and rawB will not be used at all in the function.


returns the list spotConfig with two new entries:
spotConfig$seq.modelFit fit of the model used with predict()
spotConfig$seq.largeDesignY the y values of the design, evaluated with the fit
