Solution

The correct answer is:

b. No

Explanation:

Kriging, particularly Gaussian process regression, is a type of interpolation method that focuses on minimizing the prediction error variance rather than maximizing it. In Kriging, the predictor is designed to provide optimal estimates by taking into account the spatial correlation between sampled points.

The goal is to minimize the variance of the prediction error at unknown locations, rather than maximizing it. By incorporating the covariance structure of the process being modeled, Kriging effectively provides a more accurate prediction that enhances the reliability of the forecasts, particularly in spatial analysis and geostatistics. Thus, the variance of the prediction error is minimized rather than maximized.
