What is the difference between "priors" and "likelihood"?
The likelihood is the joint density of the data, given a parameter value and the prior is the marginal distribution of the parameter. Something tells me you're asking something more though-- can …

maximum likelihood - Invariance property of MLE: what is the MLE …
That's not exactly what Casella and Berger say. They recognize (page 319) that when the transformation is one-to-one the proof of the invariance property is very simple. But then they …
maximum likelihood - Basic question about Fisher Information …
It follows that if you minimize the negative log-likelihood, the returned Hessian is the equivalent of the observed Fisher information matrix whereas in the case that you maximize the log …
Likelihood Ratio Test for Poisson Distribution
We want to construct a likelihood ratio test to see if a Poisson distribution is suitable to describe the data. The likelihood and log-likelihood equations for a Poisson distribution are:
What is the conceptual difference between posterior and …
Oct 3, 2019 · 2 To put simply, likelihood is "the likelihood of $\theta$ having generated $\mathcal {D}$ " and posterior is essentially "the likelihood of $\theta$ having generated $\mathcal {D}$ " …
definition - What's the difference between likelihood and …
I agree that the likelihood doesn't need to be normalized, but for a particular data set the likelihood function is considered a measurable mapping from parameter space to R. You can use that …
What is the difference between "likelihood" and "probability"?
Mar 5, 2012 · The wikipedia page claims that likelihood and probability are distinct concepts. In non-technical parlance, "likelihood" is usually a synonym for "probability," but in statistical …
r - AIC, likelihood, loglikelihood confusion - Cross Validated
I think the confusion may be due to thinking of the log-likelihood when you are really looking at the log of the likelihood ratio (likelihood for model1/likelihood for model2). So depending on which …
How to calculate the likelihood function - Cross Validated
Jan 10, 2015 · My question is, how do I determine the likelihood function? I looked up the pdf of the exponential distribution, but it's different. So is the likelihood function always given to me in …
