# Bayes an essay towards solving a problem

Bayesian probability is an interpretation of the concept of probability , in which, instead of frequency or propensity of some phenomenon, probability is interpreted as reasonable expectation [1] representing a state of knowledge [2] or as quantification of a personal belief. The Bayesian interpretation of probability can be seen as an extension of propositional logic that enables reasoning with hypotheses; [4] that is, with propositions whose truth or falsity is unknown. In the Bayesian view, a probability is assigned to a hypothesis, whereas under frequentist inference , a hypothesis is typically tested without being assigned a probability. Bayesian probability belongs to the category of evidential probabilities; to evaluate the probability of a hypothesis, the Bayesian probabilist specifies a prior probability.

### Bayes Theorem Definition and Examples

Bayes Theorem is the handiwork of an 18th-century minister and statistician named Thomas Bayes, first released in a paper Bayes wrote entitled "An Essay Towards Solving a Problem in the Doctrine of Chances. There is some debate among economists on whether credit should also be given to another economist, Richard Price, who edited and corrected Bayes' paper in , after his death in Another wrinkle on Bayes Theorem stems from a paper by French mathematician Pierre-Simon Laplace, who was apparently unaware of Bayes original thesis.

In analysis Laplace introduced the potential function and Laplace coefficients. He also put the theory of mathematical probability on a sound footing. View twelve larger pictures. Biography Pierre-Simon Laplace 's father, Pierre Laplace, was comfortably well off in the cider trade. Many accounts of Laplace say his family were 'poor farming people' or 'peasant farmers' but these seem to be rather inaccurate although there is little evidence of academic achievement except for an uncle who is thought to have been a secondary school teacher of mathematics.
