Modified Wald Test for Group Wise Heteroskedasticity
| Conventional Banks | Islamic Banks | ||
|---|---|---|---|
| H0: σi2=σ for all i | If H0 is rejected (p-value < 0.05) → there is heteroskedasticity | H0: σi2 = σ for all i | If H0 is rejected (p-value < 0.05) → there is heteroskedasticity |
| χ2(58) = 24998.38 | χ2(26) = 7755.73 | ||
| p-value = 0.0000 | p-value = 0.0000 | ||
