The article here says: |

"<b>Likelihood</b> is a function of how likely an event is, which is <b>weaker than probability</b> (or odds in favor)." |

I know likelihoods and probabilities fairly well, but I have <b>no idea what this is saying</b>. As pointed out clearly in [[Likelihood_function|Likelihood function]], the true difference is as follows: |

"<b>likelihood function (often simply the likelihood) is a function of the parameters of a statistical model... that is <math>\mathcal{L}(\theta |x) = P(x | \theta)</math>.</b>" |

Saying they are weaker makes it sound like they are somehow capturing the same idea, but that likelihood has weaker confidence or some such. |

- Yes. I don't think it should even be labelled as a dab page, as it could be massively expanded. The book I cited, (James franklin, the science of conjecture) seems to be an excellent source for probabilistic reasoning before the invention of math -- goes back to insurance contracts for shipping in ancient egypt, greece, and various legal cases 500BC to 1500 AD that deal with the "likelihood" that something may or may not happen.

"Weaker??"
The article here says:
"Likelihood is a function of how likely an event is, which is weaker than probability (or odds in favor)."
I know likelihoods and probabilities fairly well, but I have no idea what this is saying. As pointed out clearly in Likelihood function, the true difference is as follows:
"likelihood function (often simply the likelihood) is a function of the parameters of a statistical model... that is ."
Saying they are weaker makes it sound like they are somehow capturing the same idea, but that likelihood has weaker confidence or some such.
