Loop over consecutive values forvalues 只能用于数值的循环 *Synax forvalues lname = range { Stata commands referring to `lname' } 对于while中方程求解例子,我们也可以用forvalues来做,假如我们猜到解在1-3范围内 forvalues x_est = 1(0.0001)3{
My main argument is that user-written Stata packages are thesource of learningadvanced Stata programming. In general, any program - whether it is written by Stata staff or a Stata user - intends to solve a problem or facilitate a task. While other users can get benefit from using the progr...
