Display likelihood function in Bayesian tests?
There most probably will be a very simple answer to this, but just asking for a friend (i.e., my med/bio undergrads)...
In JASP's Bayesian analysis output, plots show the prior and posterior parameter distributions. Why is the likelihood not shown? I think this would be great for educational purposes: the posterior distribution is between the prior and likelihood and can be closer to the former or the latter.
This would illustrate nicely a basic idea of Bayesian analysis: the update of a prior belief by observed data. The closer the posterior to the likelihood, the stronger the evidence the data provide. It also gives a complete picture of Bayes' equation: posterior = likelihood x prior.
Thanks for your input!
