Fuzzy Regression Models with Fuzzy Random Variables: Application in the Social and Economic Fields

The human capital stock of the firm, accumulated through educational and training activities, is one of the main factors of production and economic growth. From the firm’s perspective, the aim of the human capital investment is to increase productivity; instead, for the employees, the primary aims of the education and training are the effects on their wages and carriers. Our paper focuses on the analysis of the determinants that can affect the performance of employees in a training course. In particular, it is proposed a fuzzy regression model to analyze the dependence of the dependent variable "vote" by some independent fuzzy and crisp variables.
