What is the conceptual difference between posterior and …
Oct 3, 2019 · The likelihood is a pdf, it's just normalised w.r.t all possible data outcomes, and the posterior is a pdf, but it's normalised w.r.t all possible parameter values Even if the likelihood …
What is likelihood actually? - Cross Validated

probability - What exactly is likelihood? - Cross Validated
Nov 15, 2023 · The likelihood is the proportion of probability at (infinitely close to) any x in X. Then how do we interpret values such as 2, 3 etc. (above 1), that within this infinitely small interval …
Likelihood vs. Probability - Cross Validated
It is, however, proportional to a probability density, which is why we say it is a likelihood of p p being a particular value given the sample--it represents, in some sense, the relative plausibility …
Why is everything based on likelihoods even though likelihoods …
Feb 18, 2024 · Even though the correct likelihood (i.e. 5,5) is bigger than the incorrect likelihood (i.e. 6,6), both are still so small! So how come in statistics, everything is based on likelihoods …
estimation - Likelihood vs quasi-likelihood vs pseudo-likelihood …
