Modeling and forecasting were performed based on Gaussian, Student’s t and GED distribution densities with a view to identifying the best distribution for examining stylized facts about the volatility of returns. Initial tests of heteroscedasticity (ARCH-LM), autocorrelation and stationarity were carried out to establish specific data requirements before modeling. Results for conditional variance indicated the presence of significant asymmetries, volatility clustering, leptokurtic distribution, and leverage effects. Effectively, PARCH (1,1) under GED distribution provided highly significant results free from serial correlation and ARCH effects, thus revealing the asymmetric responsiveness and persistence to shocks. Forecasting was performed across distributions & assessed based on symmetric lost functions (RMSE, MAE, MAPE & Thiel’s U) and information criteria (AIC, SBC & Loglikelihood). The information criteria offered a preference for EGARCH (1,1) under GED distribution while symmetric lost functions provided very competitive choices with very slight precedence for GARCH (1,1) and EGARCH (1,1) under GED distribution. Following these results, it’s recommended that PARCH (1,1) and EGARCH (1,1) be respectively preferred for modeling and forecasting volatility with GED as the choice distribution. Given the asymmetric responsiveness and persistence of conditional variance, macroeconomic & fiscal adjustments in addition to stabilization of the internal political environment are advised for Uganda. </p><p><strong>Keywords: </strong>Forecasting volatility, GARCH family Models, Probability Distribution Density, Forecast accuracy.</p><p><strong>JEL Classifications: </strong>C58, C53, G17, F31</p><p>DOI: <a href="https://doi.org/10.32479/ijefi.9016">https://doi.org/10.32479/ijefi.9016</a></p>}, number={2}, journal={International Journal of Economics and Financial Issues}, author={Erkekoglu, Hatice and Garang, Aweng Peter Majok and Deng, Adire Simon}, year={2020}, month={Mar.}, pages={268–281} }
