Constructor Detail

DoubleExponentialSmoothingTest

public DoubleExponentialSmoothingTest(java.lang.String name)

Constructor required by the JUnit framework.

Method Detail

testConstantDoubleExponentialSmoothing

public void testConstantDoubleExponentialSmoothing()

A simple exponential smoothing test where the observed data is constant. This should result in the same constant forecast for any value of the smoothing constant.

testDoubleExponentialSmoothing

public void testDoubleExponentialSmoothing()

A somewhat more realistic test where the results are known (and were calculated independently of the model). Validates that the DoubleExponentialSmoothingModel returns the expected set of results for the given inputs.
