Abstract

Abstract: In order to solve the computing complex problems of the parameter estimation to the logistic regression models，a novel method to estimate parameter is presented based on particle swarm optimization algorithm.Maximum likelihood estimation is adopted to be fitness function for the optimization problem.Thus the model of computing parameter to the logistic regression models is set up.The numerical simulation results show that PSO algorithm can be used to calculate the parameters of the logistic regression models.
