Detailed Description

Average Change of Previous Years prediction method.

A somewhat trivial relative prediction method that calculates the monthly changes in previous years, takes a monthly average of them, and applies them to the predicted year.

This has proven to be a rather good prediction method for many cases.

Member Function Documentation

Ref< Matrix > predict (  const Matrix &    testdata, int    startmonth )  const [virtual]

Tests the data and returns the monthly predictions in matrix. Must be implemented by prediction strategies. Parameters: startmonth  See train(). Reimplemented from PredictionStrategy. Definition at line 295 of file prediction.cc.

void train (  const Matrix &    traindata, int    startmonth )  [virtual]

Trains the learning method with the given data. Must be implemented by prediction strategies. Parameters: startmonth  Zero-based month number for the first sample in the data. The month number can be in range 0-11, but only the last two digits are interpreted as months, so it can have values like 199905 or 9905. Parameters: traindata  Data for training the method. startmonth  Starting month of the data. Reimplemented from PredictionStrategy. Definition at line 264 of file prediction.cc. References PredictionStrategy::rowDeltas().
