Java statistics package for Robust Statistics

Question

I'm looking for a java package for "Robust Statistics". Please Note the meaning of "Robust" here.

I know about Apache commons Math Descriptive statistics and Summary Statistics but they only provide non-robust statistics.

An example here would be median absolute deviation

Answer 1

I am not sure whether this will give you an exact solution. But you can derive those features using apache math library. This is an example for deriving mean absolute deviation.

public double mad(double [] autoCorrelationValues){
    double [] tempTable = new double[autoCorrelationValues.length];
    Median m = new Median();
    double medianValue = m.evaluate(autoCorrelationValues);
    for(int i=0 ; i<autoCorrelationValues.length ;i++){
        tempTable[i] = Math.abs(autoCorrelationValues[i] - medianValue);
    }
    return m.evaluate(tempTable); 
}
