Detailed Description

Previous Year prediction method.

A trivial prediction method that always predicts same values as in the corresponding months in the previous year.

Any sophisticated prediction method should do better than this.

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 494 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.

Reimplemented from PredictionStrategy.
