总结 predict命令是stata中一个非常常用的命令，可以用来生成模型预测值和残差值。 我们可以使用各种选项来控制预测值或残差值的生成方式，也可以使用predict命令来预测新的数据或者组合多个模型的预测值。 掌握predict命令的用法对于进行统计分析是非常重要的。.. Predict is for use by programmers as a subroutine for implementing the predict command for use after estimation.. Because predict makes its calculations on the basis of the recorded coefficients and the data in memory, predict can do more than calculate predicted values for the data on which the estimation took place—it can make outofsample predictions, as well.. I am totally new to stata, and i have a brief question about running individual cross sectional regression and obtaining residuals..
