  1. Notes:* Indicates significant at 5% confidence interval
  2. The null hypothesis for the: Wooldridge test is Ho: no serial correlation; Pesaran CD test is Ho: no cross-sectional dependence; MWALD heteroscedasticity test is Ho: Presence of homoscedasticity or constant variance. Residual normality test is Ho: Residuals are normally distributed
