Bayesian probability, statistics, and inference are interconnected concepts within the Bayesian framework, but they focus on different aspects:
-
Bayesian Probability: This is an interpretation of probability as a measure of belief or certainty about an event, rather than a frequency of occurrence. It allows for the updating of probabilities as new evidence is introduced, using Bayes’ Theorem.
-
Bayesian Statistics: This is a statistical paradigm that applies Bayesian probability to statistical analysis. It involves using prior distributions to express beliefs about parameters before observing data, and updating these beliefs with the data to obtain posterior distributions.
-
Bayesian Inference: This is the process of using Bayesian statistics to draw conclusions about unknown parameters. It involves calculating the posterior distribution of the parameters given the observed data, which can then be used for prediction, decision-making, or hypothesis testing.
In summary, Bayesian probability provides the foundation, Bayesian statistics applies this foundation to data analysis, and Bayesian inference is the process of drawing conclusions from the analysis.
