Re: st: save coefficients from a fixed effect regression. Plotting regression coeﬃcients and other estimates in Stata Ben Jann Institute of Sociology University of Bern ben.jann@soz.unibe.ch September 18, 2017 Abstract Graphical presentation of regression results has become increasingly popular in the scientiﬁc literature, as graphs are much easier to read than tables in many cases. where c is a bunch of category dummy variables (and G is the associated coefficient). The good news is that we can still find different regression components using asreg. I am running 1000 or so regressions using a foreach loop and would like to export the results (mainly just the regression coefficients) to Microsoft Excel. EJMR | Job Market | Candidates | Conferences | Journals | Night Mode | Privacy | Contact. I know that STATA will save the estimated G's in a system variable: _b[G_i] (where i indexes each coefficient). The first value of the new variable (called coef1 for example) would the coefficient of the first regression, while the second value would be the coefficient from the second regression. Re: st: "bsample" and "set seed" together do not work! Save coefficients to a matrix. Use the following steps to perform linear regression and subsequently obtain the predicted values and residuals for the regression model.

Step by Step Guide to Estimate “Simple Linear Regression Model” Using Stata. From: Maarten buis Prev by Date: Re: st: "bsample" and "set seed" together do not work! When you run a regression, Stata saves relevant bits of these regressions in scalars and matrices saved in different r() and e() levels, which can be viewed by -return list- and -ereturn list- commands, respectively. The first value of the new variable (called coef1 for example) would the coefficient of the first regression, while the second value would be the coefficient from the second regression. Downloadable! >*--------------------- end example ------------------ >From: Maarten buis That's the stuff to add indicated by a comment above. It is called coefplot. There is considerable variation as to what is stored: command tab1 stores only the number of cases and the number of rows, other procedures store a wealth of information. Stata can store estimates from multiple models, save all estimates in a single table, and export the table to an external file, such as rtf, csv, html, tex, and others.This is possible with the .esttab command from the estout package, which you can install from the Stata packages repository..

Most Stata procedures store some, many or perhaps all elements that were used during computation in memory from which they can be retrieved; they remain available until the next procedure produces new elements to be stored. Also, I don't really now how to turn those into variables. forval i = 1/50 {reg y x`i'' control1 control2, r gen coeff_xi' = _b[xi']} or something along those lines . but nothing in your code accesses standard errors; nevertheless they can also be saved using statsby.
