WitrynaThe Newton Raphson algorithm is an iterative procedure that can be used to calculate MLEs. The basic idea behind the algorithm is the following. First, construct a quadratic approximation to the function of interest around some initial parameter value (hopefully close to the MLE). Next, adjust the parameter value to that which maximizes the ... Witryna20 sie 2024 · The spline coefficients are calculated using the spline (x,y) interface (for natural spline) or spline (x,y,dy_1,dy_n) for known end slopes. The spline coefficients are stored together with the input (x,y) nodes in a user-defined type called spline. Evaluation of the spline, and its derivatives are done with value (x), slope (x) and slope2 (x ...
