回帖推荐zhaosweden 发表于2楼 查看完整内容 For cross-sectional data, classical assumptions include random sampling. However, based on random sampling, "serial correlation" in the error terms is not a problem at all. This becomes interesting with TS data and Panel ones. if yo consider the correlation between the errors and the regressors, then this becomes a mispecification problem.
