摘要翻译：
利用McFadden(1974)关于条件logit估计的结果，我们证明了具有固定效应的二元logit模型的条件极大似然估计的存在唯一性与数据点的配置之间存在一一映射。我们的结果推广了Albert和Anderson(1984)关于横截面情形的结果，并可用于建立一个在有限样本中检测虚假估计的简单算法。作为一个例子，我们展示了一个人造数据集，stata的命令\texttt{clogit}为其返回虚假的估计值。

英文摘要：
  By exploiting McFadden (1974)'s results on conditional logit estimation, we show that there exists a one-to-one mapping between existence and uniqueness of conditional maximum likelihood estimates of the binary logit model with fixed effects and the configuration of data points. Our results extend those in Albert and Anderson (1984) for the cross-sectional case and can be used to build a simple algorithm that detects spurious estimates in finite samples. As an illustration, we exhibit an artificial dataset for which the STATA's command \texttt{clogit} returns spurious estimates.
