WebThe Fisher information for the more general two parameter beta case seems at least potentially doable. So to begin with, you might take the negative of the second derivative of the log-likelihood with respect to $\lambda$ and try to find the expectation of that quantity, and see if you can do it the 'standard' way. WebInformative priors. An informative prior expresses specific, definite information about a variable. An example is a prior distribution for the temperature at noon tomorrow. A reasonable approach is to make the prior a normal distribution with expected value equal to today's noontime temperature, with variance equal to the day-to-day variance of …
