WebOct 11, 2015 · I know there is an analytic solution to the following problem (OLS). Since I try to learn and understand the principles and basics of MLE, I implemented the fisher scoring algorithm for a simple linear regression model. y = X β + ϵ ϵ ∼ N ( 0, σ 2) The loglikelihood for σ 2 and β is given by: − N 2 ln ( 2 π) − N 2 ln ( σ 2) − 1 2 ... WebThe Fisher information attempts to quantify the sensitivity of the random variable x x to the value of the parameter \theta θ. If small changes in \theta θ result in large changes in the likely values of x x, then the samples we observe tell us a lot about \theta θ. In this case the Fisher information should be high.
