Abstract: This paper has two major objectives. First, we develop and implement a Bayesian generalized factor model that allows for non-orthogonality of the idiosyncratic factors and the flexibility of cross-sectional and time series dimensions. Second, we evaluate the significance of the orthogonality assumption in factor models, a controversial assumption discussed in the recent literature. To this end, we propose a simple methodology to choose the generalized factor model that best determines the idiosyncratic correlations and provide a comparative analysis between the classical and generalized factor models. The proposed methodology is applied to both the simulated data and the foreign exchange rate data.
