The inference in probit models relies on the assumption of normality. However tests of this assumption are not implemented in standard econometric software. Therefore the paper presents a simple representation of the Bera-Jarque-Lee test that does not require any matrix algebra. Furthermore the representation is used to compare the Bera-Jarque- Lee test with the RESET-type test proposed by Papke and Wooldridge (1996). -- probit model ; Lagrange multiplier test ; normality assumption ; artificial regression |
