Method Detail

testConstantWeightedMovingAverage

public void testConstantWeightedMovingAverage()

A simple weighted moving average test where the observed data is constant. This should result in the same constant forecast.

testWeightedMovingAverage

public void testWeightedMovingAverage()

A somewhat more realistic test where the results are known (and were calculated independently of the model). Validates that the WeightedMovingAverageModel returns the expected set of results for the given inputs. This is still not a great test, since the weights are all equal - at 0.25 - so it is equivalent to a four period moving average. Could do with some better test data here.
