One use case that may be of particular interest is updating a prior on a parameter B based on b,
an a statistical estimate of B (for example from a study you conducted or are reading about).

- If b is a
**mean**or a difference in means (such as a**treatment effect**), the likelihood distribution will be a normal distribution centered around b with a standard deviation equal to the standard error of b. The log-normal distribution may be a good choice of prior for positive quantities.
