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 ...

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 ...

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.
