Finally, the RDFA algorithm can be extended to predict electricity price in a longer period using a multi-factor model by capturing trends in different time horizon.  ...  To reduce the arithmetic complexity, we propose a recursive dynamic factor analysis (RDFA) algorithm where the PCs are recursively tracked using efficient subspace tracking algorithm while the PC scores  ...  for Gaussian input. and are forgetting factors with values slightly smaller than 1.  ...
