Outline of Final Research Achievements 
1) The method of causal analysis by Weber, which is known as “adequate causation”, was imported from the methodological research by Johannes von Kries, who is one of the most famous biologist and statistician in the second half of 19 century in Germany.2) Von Kreis already defined causality counterfactually and measured it with the concept of probability. Therefore his “adequate causation” is the very proto type of Statistical Causal Inference in these days, and so Weber’s causal analysis also shares the same framework. 3) Weber's more wellknown method, socalled “interpretative sociology” is also reconstructed with the framework of another wellknown statistical inference, Bayes statistics. In this reconstruction, indeterminacy of meaning of social action is seen as one kind of indeterminacy in Bayesian inference, the extent of which depends on size of observations. Therefore, indeterminacy of meaning of action also depends on the chance of its observation.
