Definition of posterior probability in English:

posterior probability


  • The statistical probability that a hypothesis is true calculated in the light of relevant observations.

    • ‘To summarize: the paradox arises because you use the prior probabilities to calculate the expected gain rather than the posterior probabilities.’
    • ‘The expectations are actually obtained using the posterior probabilities rather than the prior probabilities.’
    • ‘They implemented a full Bayesian method for calculating posterior probabilities using Markov Chain Monte Carlo.’
    • ‘If the null hypothesis is rejected, the program calculates a posterior probability for functional divergence for each position in the alignment.’
    • ‘Within the Bayesian framework, the posterior probability is obtained from the likelihood function and the prior probability.’
