AggregationFunctionEvaluator evaluator(AggregationFunction aggregationFunction,

                                       double[] fieldWeights,
                                       double[] missingValueWeights,
                                       double[] similarityScales,
                                       double pParameter)
```
    Creates an AggregationFunctionEvaluator instance. Compare function, field weights, missing value weights and similarity scales at index i must correspond to cluster and data vector values at the same index, that will be passed in at the evaluation phase to the AggregationFunctionEvaluator#evaluate() method.
    
    Parameters:
    
    aggregationFunction - the AggregationFunction to be evaluated
    
    compareFunctions - the CompareFunctions to measure distance/similarity between the vectors
    
    fieldWeights - field weights for each field/its values
    
    missingValueWeights - missing value weights for each field/its values
    
    similarityScales - similarity scales for each field/its values
    
    pParameter - the p-parameter, only used by the Minkowski function
