The term after the minus sign is the Newton-Raphson step. If the likelihood function evaluated at is less than that evaluated at ,then is recomputed using half the step size. The iterative scheme ...

Newton's Method: Newton's Method is a technique for approximating a root to an equation of the form f (x) = 0. What is required is an initial estimate for the root, called x 1, and an iterative ...

Brian Cox outlines the historical context of the era in which Newton began to be interested in the nature of the visible spectrum obtained using a prism.
