Discrepancies between assumed dynamical models and observations are often handled by making further probabiIistic assumptions, a tactic which has both strengths and weaknesses. A re-examination of filtering and smoothing is conducted, and an alternative multicriteria approach, which is probability free, is advanced. This approach involves vector minimization as a key ingredient, and it speciali...
