TY - JOUR T1 - Bayesovská štatistika A1 - Pázman, Andrej JA - Obzory matematiky, fyziky a informatiky Y1 - 2004 VL - 33 IS - 1 SP - 1 EP - 14 SN - 1335-4981 N2 - The basic aim of the paper is to put attention of the teachers to the historically first statistcal theory - the Bayesian statistics. The paper starts by simple arguments in favour of the statment that probability helps to detect the causes of emprical facts. Some basic properties of the Bayes formula are presented on an elementary level: the chain rule, the possibility to detect the true cause after a largte number of observations, the necessity to have some prior knowledge for understanding an empirical event, the subjective nature of the prior. On simple examples the paper shows that the information content of an empirical fact depends also on the prior knowledge of the observer of the fact. The relation of Bayesian statistics to classical statistics is considered to a certain extend. ER -
