Fisher Information and the Cramer-Rao Lower Bound - Coursera

WebSo this expression right here is the variance of the binomial distribution, which you can recall or lookup. But that variance is n times p times one minus p. If we plug that in and we simplify, we get this expression for our Fisher information, don't forget, we don't just want the Fisher information, but the entire Cramér–Rao lower bound. WebInformative priors. An informative prior expresses specific, definite information about a variable. An example is a prior distribution for the temperature at noon tomorrow.
