Confidence intervals & credible intervals

This is a note for me.

Confidence intervals: “Are the observed data x reasonable given the hypothesised values of θ?” == P(θ| x)

vs

Credible intervals: “What values of θ are reasonable given the observed data x?” == P(x| θ)

Those are related as “P(θ| x) = P(θ)P(x| θ)”

Credible intervals are part of Bayesian approach.
