Alternative approach to evaluating interpolation methods of small and imbalanced data sets
(Wydawnictwa AGH, 2017) Gonet, Tomasz; Gonet, Kamil
The research concerns an alternative approach to the evaluation of interpolation methods for mapping small and imbalanced data sets. A basic statistical analysis of the standard cross-validation procedure is not always conclusive. In the case of the investigated data set (which is inconsistent with normal distribution), three interpolation methods have been selected as the most reliable (according to standard cross-validation). However, maps resulting from the aforementioned methods clearly diff er from each other. This is the reason why a comprehensive statistical analysis of the studied data is a necessity. We propose an alternative approach that evaluates a broadened scope of parameters describing the data distribution. The general idea of the methodology is to compare not only the standard deviation of the estimator but also three additional parameters to make the final assessment much more accurate. The analysis has been carried out with the use of Golden Software Surfer. It provides a wide range of interpolation methods and numerous adjustable parameters.
