In order to implement sustainable groundwater resources management, it is necessary to Model the behavior of groundwater level. Groundwater is a nonlinear and complex system which Data-driven Models can be Modeled this system without approximation and simplification. This study evaluates the perform... ادامه
کلیدواژه: The results show that applying the hybrid model increases the predictive power of realized return compared to other research models
نویسندگان: Asima Mehdi, Abbaszadeh Asl Amir Ali
ناشر: تحقیقات مالی - Financial Research Journal
Objective: Capital asset pricing Model (CAPM) has been among the most common Models to estimate the expected return. In the standard CAPM Model, a) the beta coefficient is fixed and b) the relationship between stock returns and market returns is assumed to be linear. While in financial markets, it i... ادامه
