In spite of popularity and theoretical simplicity of the one-factor CAPM used in the valuation of financial assets, more attention is now made to the important extension proposed by Fama and French  rising the Three-Factor Pricing Model (TFPM). Alongside beta, average stock returns could be explained by some size and book-to-market supplementary effects.

To account for inter-individual heterogeneity, estimation of the coefficients is conducted according to random-coefficient specifications within the context of panel data analysis.
