Karim Ivaz Faculty of Mathematical Sciences, University of Tabriz, Tabriz, Iran. Hamzeh Beiranvand Department of Electrical Engineering, Lorestan University, Khoramabad, Lorestan, Iran. Journal Article 2018 05 25 This paper introduces a novel method for estimation of the parameters of the constant elasticity of variance model. To do this, the likelihood function will be constructed based on the approximate density function. Then, to estimate the parameters, some optimization algorithms will be applied.
