## Dropping i.dummies from regression | asdoc | Word | Stata

Category:asdoc,Blog,Stata ProgramsQuestions: 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. How can I do that?

If you have not already installed asdoc, you can install it from SSC by typing the

ssc install asdoc

Let’s use an example data set.

use http://fintechprofessor.com/regdata.dta, clear

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

asdoc reg y x1 x2 x3 i.year i.location, nest drop(i.year i.location) replace asdoc reg y x1 x2 x4 i.year i.location, nest drop(i.year i.location)

### Explanations

In the above two lines, we have estimated two regressions and sent their output to a Word file. 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. The option * nest *will create a nested regression table. The option

**drops these dummy variables from the regression table, however, they are included in the main regression. The two lines produce the following regression table in MS Word.**

*drop(i.year i.location)*[mc4wp_form id=”1409″]

November 19, 2018at 4:49 amIs there any option to include Year_Dum Yes or no Location_dum yes or no in the results? If we want to include the order of the variables in the table such as _cons x1 x2 x3 etc, do we have options?
