The two lines produce the following regression table in MS Word. The option drop(i.year i.location) drops these dummy variables from the regression table, however, they are included in the main regression. The option nestwill create a nested regression table. In the first line, we estimated a regression with the three main independent variables x1, x2, and x3 and included the year and location dummies on the fly. In the above two lines, we have estimated two regressions and sent their output to a Word file. Let us estimated the following regression: asdoc reg y x1 x2 x3 i.year i.location, nest drop(i.year i.location) replaceĪsdoc reg y x1 x2 x4 i.year i.location, nest drop(i.year i.location) Explanations This dataset has four main independent variables, named as x1, x2, x3, x4 and a set of possible dummy variables that will be constructed from the variable year (from 2001-2005) and location (from 1-3).

If you have not already installed asdoc, you can install it from SSC by typing the following in the Stata command window: Questions: I have time and location dummies which I want to include in the regression, but do not want to report them in the regression nested tables created with asdoc. Stata codes for event study methodology.The implied cost of capital (ICC) | GLS model | Stata | Gebhardt et al.will delete the variables listed after drop from your data.

If this doesn't clarify, download dataex using ssc inst dataex and show us a reproducible example of your. Therefore you can't destring it and the test for missing would be (e.g.) sprcode. Once you have eliminated observations, you cannot read them back in again. Warning: drop and keep are not reversible. keep works the same way as drop, except that you specify the variables or observations to be kept rather than the variables or observations to be deleted.

What is the R equivalent of STATA's 'drop' command?
