function [f, df, d2f, R2] = likelihood_quadratic_approximation(particles, likelihoodvalues)
|
||||
|
||||
% Approximate the shape of the likelihood function with a multivariate second order polynomial.
|
||||
%
|
||||
%
|
||||
% INPUTS
|
||||
% - particles [double] n×p matrix of (p) particles around the estimated posterior mode.
|
||||
% - likelihoodvalues [double] p×1 vector of corresponding values for the likelihood (or posterior kernel).
|
||||
%
|
||||
% OUTPUTS
|
||||
% - f [handle] function handle for the approximated likelihood.
|
||||
% - df [handle] function handle for the gradient of the approximated likelihood.
|
||||
% - d2f [handle] Hessian matrix of the approximated likelihood (constant since we consider a second order multivariate polynomial)
|
||||
% - R2 [double] scalar, goodness of fit measure.
|
||||
%
|
||||
% REMARKS
|
||||
% [1] Function f takes a n×m matrix as input argument (the function is evaluated in m points) and returns a m×1 vector.
|
||||
% [2] Funtion df takes a n×1 vector as input argument (the point where the gradient is computed) and returns a n×1 vector.
