摘要： Our study extends work on econometric computing issues in logit regression models by focusing on observation-specific and group dummy variables, wherein all or nearly all of the members of the group are associated with the same value for y , rather than the case of continuous regressors. To make our case, we employ a small data set from a previously published study. Lastly, we explore, using various econometric software packages, several prescriptions for dealing with these issues.
