In this video, we introduce the Newton-Raphson method, and how it can be used to optimize one-variable functionals, and also how it can be used to numericall A tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. The term exp(r*t) in the expression for f should read exp(-r*t) if the expression for f1 is correct. So f should be defined as. f <- s0*pnorm(d1)-E*exp(-r*t)*pnorm(d2)-c Then the output will be [1] 0.1000000 0.1877024 0.1876218 0.1876218 Finally do not use c as variable name; c is a builtin function. Use something like C or even better Cxx. A R implementation of the Raphson-Newton method.

This is an implementation of the well-known Newton-Raphson algorithm to find a real root, r, a < r < b, of the function f. Initial values, r_0 say, for the algorithm are internally computed by drawing 'n.Seq' equally spaced points in (a, b).Then, the function f is evaluated at this sequence. Finally, r_0 results from the closest image to the horizontal axis. Details. This algorithm is used on the logitModel regression estimation function.. Value. A list with maximum likelihood estimation results for further computation. References.
