SpletΠ = product (multiplication). The log of a product is the sum of the logs of the multiplied terms, so we can rewrite the above equation with summation instead of products: ln [f X (x 1) * f X (x 2) * … * f X (x n )] =. The above relationship leads directly to the log likelihood function [2]: l (Θ) = ln [ L (Θ)].

This occurs for example when complex simulator-based statistical models are fitted to data, and synthetic likelihood (SL) method is used to form the noisy log-likelihood estimates using computationally costly forward … Splet24. mar. 2024 · The log-likelihood function F(theta) is defined to be the natural logarithm of the likelihood function L(theta). More precisely, F(theta)=lnL(theta), and so in particular, defining the likelihood function in expanded notation as L(theta)=product_(i=1)^nf_i(y_i theta) shows that F(theta)=sum_(i=1)^nlnf_i(y_i theta). … new york state procurement
