Abstract
This research investigates the effects of heteroscedasticity and periodicity in a Panel Data Regression Model (PDRM) of audit fees for commercial banks. PDRMs are often associated with these effects, of which previous attempts to model audit fees have failed to investigate. This study thus explored this phenomenon by extending the existing works within the context of fitting an audit fee model and derivation of a Joint as well as conditional Lagrange Multiplier (LM) test via a two-way error component model. LM test results showed that the tests have good size and power as all the three tests are significant at 5%. Results were achieved through the empirical study of real-life data sourced from the banks’ annual published accounts. Both LSDVM and REM captured the goodness of fit better when compared to the POLS model. However, the Hausman test revealed that LSDVM is most preferable.
