Fix that, and the correct result should follow.

WebSep 17, 2024 · For a Poisson random variable, the Fisher information (of a single observation) is 1/ λ (the precision or inverse variance). For a sample you have either expected or observed information. For expected … Webinformation. More generally, replacing the Poisson distribution by the richer class of compound Poisson distributions on the non-negative integers, we define two new “local information quantities,” which, in many ways, play a role analogous to that of the Fisher information for a continuous random variable. We
WebIn probability and statistics, the logarithmic distribution (also known as the logarithmic series distribution or the log-series distribution) is a discrete probability distribution derived from the Maclaurin series expansion. This leads directly to the probability mass function of a Log ( p )-distributed random variable : for k ≥ 1, and ... Webup the Fisher matrix knowing only your model and your measurement uncertainties; and that under certain standard assumptions, the Fisher matrix is the inverse of the covariance matrix. So all you have to do is set up the Fisher matrix and then invert it to obtain the covariance matrix (that is, the uncertainties on your model parameters).
