The aim is to demonstrate that the presence of different levels of this variable influences the outcome of a regression, making it significant or not. 2018-01-18 2016-08-10 We can use e (sample) to generate predicted values only for those cases used to estimate the model. Below we use predict to generate a new variable, p2, that contains predicted values, but this time we add if e (sample)==1, which indicates that predicted values should only be created for cases used in the last model we ran. 2014-11-15 · e (sample) in Stata – If so, how? e (sample) in Stata Here is a nice way to see which observations are being used in the models you run in Stata. Basically, the function e (sample) stored in the ereturn list indicates with 1 the observations being used, and zero otherwise.
