Statistics stores a number of double values and computes descriptive statistics out of them.
The element is just an object of the DescriptiveStatistics class in the Apache Common numerics library.
To add a statistics element to your model, simply drag the icon element to the list of your model elements.
A call to the element method void addValue(double value) adds a double value to the dataset.
A call to the element method void clear() clears all data previously added.
The element provides several methods to retrieve descriptive statistics out of the data added. Here are just two of them:
statistics.clear(); // Make sure the dataset is empty statistics.addValue(1); statistics.addValue(1); statistics.addValue(1); statistics.addValue(2); _println("Mean = "+statistics.getMean()); // prints: Mean = 1.25 _println("Variance = "+statistics.getVariance()); // prints: Variance = 0.25
