Note(s): a, b and c indicate significance at 1%, 5% and 10%, respectively. Figures in parenthesis are p-values; LM: the Lagrange multiplier test of residual serial correlation. ARCH: autoregressive conditional heteroscedasticity test of residuals. Heteroscedasticity: this is based on the regression of squared residuals on squared fitted values. Normality is based on a test of skewness and kurtosis of residuals. The White test is a test for heteroscedasticity
