BAYESIANS AND FREQUENTISTS.
BAYESIANS AND FREQUENTISTS. There is a major split between statisticians. In conducting a statistical test, one grouping (“Bayesians”) wants to include independent knowledge and beliefs; the other wants to start from scratch (“frequentists”). This wikipedia article describes the “debate around the foundations of statistics: “Frequentist and Bayesian interpretations disagree about the ways in which probabilities should be assigned in applications. Frequentists assign probabilities to random events according to their frequencies of occurrence or to subsets of populations as proportions of the whole, while Bayesians describe probabilities in terms of beliefs and degrees of uncertainty.”
