In this chapter, the authors concentrate mainly on linear data models, studying the estimation of their parameters. The two cases of deterministic and random parameters are covered, but the parameters are always assumed to be time-invariant. The methods that are widely used in context with independent component analysis (ICA) are emphasized in this chapter.
