Key Concepts

Conditional Probability

Conditional probability refers to the likelihood of an event occurring given that another event has already occurred. It is fundamental in probability theory and is used to update assessments or predictions based on new information. This concept is central when evaluating outcomes that depend on a known set of conditions or events.

Bayes' Theorem

Bayes' Theorem is a powerful result in probability theory that allows for updating the probability estimate for an event as new evidence is acquired. It relates the conditional and marginal probabilities of random events, providing a way to revise prior probabilities into posterior probabilities once data is observed.

Prior Probability

Prior probability represents the initial belief or estimation about the likelihood of an event or hypothesis before new data is taken into account. It lays the foundation for Bayesian analysis, acting as the starting point which is then updated via observed evidence.

Likelihood Function

The likelihood function measures how well a particular set of parameters explains the observed data. In the context of Bayesian inference, it quantifies the probability of the observed data given a specific hypothesis or model parameters, playing a key role in updating beliefs about these parameters.

Posterior Probability

Posterior probability is the updated probability of an event or hypothesis after taking into account new evidence or data. It is computed by combining the prior probability with the likelihood of the observed data, typically via Bayes' Theorem, to provide a revised degree of belief.
