Padanalyse En Causale Modellering

Pad analysis is part of multivariate analysis and aims at describing the relation between various measurements in terms of a causal model which can be derived from a theory about the possible relations between these variables. Such a causal model can be presented in the form of an arrow diagram or pad diagram. On the basis of three examples the ingredients of a pad model are discussed, as well as the aim of pad analysis, its various forms (recursive vs. non-recursive models; models with manifest and latent variables; measurement errors). In addition causal analysis is discussed, a form of analysis which may be regarded as a generalization of pad analysis. Finally some comments are made on the state of the art and annotated references to the literature are given.
