For a lagit model, the likelihood ratia (LR) test statistic may be used ta test a null hypothesis against its alternative. The LR statistic is defined as 2 times the difference between the log likelihoods for the unrestricted and restricted madels. Here, the restricted madel is the madel a. under the restriction(s) of the null hypathesis b. under the restrictions) of the alternative hypothesis c. where the coefficients of all non-constant regressors are set ta zero d. where the coefficients of all nan-binary regressors are set ta zero e. None af the listed answers is correct
