可能定义了一个之前已经定义的scalar变量
scalar 函数是Stata的内部操作函数，它可以把计算结果做为标量保存（scalars）。它比直接使用存储在Stata变量中的数据灵活，也比Stata的标量变量更有用。它让用户可以在两个或更多变量之间建立一个标量，然后在任意计算中使用它。它们也可以用于保存操作结果，以便在其他地方使用。由于 scalar 函数可以将我们的操作保存...
发生这种情况的原因是因为Stata不允许在某些命令中使用optionse选项。解决方法：1. 尝试使用不同的命令，如果可以使用optionse选项，则可以解决问题。2. 尝试使用不同的参数，如果可以使用optionse选项，则可以解决问题。3. 尝试使用不同的数据集，如果可以使用optionse选项，则可以解决问题。4. 尝试使用不同...
More scalars. G(x*b) Cumulative “logistic” distribution. 2.2 Intercept Equation (3) has an unfortunate property. Let’s pretendx, the vector of explanatory variables, includes var1 and var2. Thus our model of the probabilities is, from (1), ...
However, adjust currently is not allowed after anova (because we can not obtain the variable names from the beta vector), areg (because predict doesn't handle the absorbed variable as expected), and multiple-equation estimation commands. adjust only uses predict. It does not use any ...

Stata 日志文件操作指南说明书
As with temporary variables, temporary scalars and matrices are automatically dropped at the conclusion of your program. 18.7.3 Temporary files In cases where you ordinarily might think you need temporary files, you may not because of Stata's ability to preserve and automatically restore the data ...
