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. Sorry, but I meant as a new single variable. Expressed in terms of the variables used in this example, the regression equation is sciencePredicted = 12.32529 + .3893102*math + -2.009765*female+.0498443*socst+.3352998*read From: Maarten buis Prev by Date: Re: st: "bsample" and "set seed" together do not work! We’ll use mpg and displacement as the explanatory variables and price as the response variable. Notice: On April 23, 2014, Statalist moved from an email list to a forum, based at statalist.org. > >-------------------------- Stata distinguishes several classes of elements, of which r(), e() and c()are most important. 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. This video is a short summary of interpreting regression output from Stata. Use regsave to store regression output regsave stores regression output Coefficients, standard errors Optionally: p-values, t-stats, confidence intervals, covariances, and more User can optionally specify: Coefficient and variance-covariance matrices Labels Table format (Abbreviated) syntax: regsave [coeflist ] [using filename ] [, Fortunately, there is a simple way out of all this. }. > No matter which software you use to perform the analysis you will get the same basic results, although the name of the column changes. It is called coefplot. 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. >(For more on examples I sent to the Statalist see: These matrices allow the user access to the coefficients, but Stata gives you an even easier way to access this information by storing it in the system variables _b and _se. (intercepts) and regression coefficients (slopes). I can see the coefficients with ereturn list and e(b) but I have trouble at getting the standard errors. > Save coefficients to … See estimation commandsfor a list of other regression commands that may be of interest.

(bcoeff supersedes deltaco by Zhiqiang Wang.) Note added 2004: this package was written for Stata 6 and is now superseded for most purposes by use of foreach or statsby in Stata 7 or 8. 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.   gen obsset = . Hi Maarten, I will try that Save coefficients to a matrix. Date 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. > Stata: Visualizing Regression Models Using coefplot Partiallybased on Ben Jann’s June 2014 presentation at the 12thGerman Stata Users Group meeting in Hamburg, Germany: “A new command for plotting regression coefficients and other estimates” ---- Original message ---- Ask Question Asked 2 years, 9 months ago. 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.. Specifically, the log likelihoodat iteration 0 does not correspond to the likelihood for the empty (or null)model. reg pric mpg weight. forval i = 1/50 { >* http://www.stata.com/support/statalist/faq statalist@hsphsun2.harvard.edu gen coeff_xi' = _b[xi'] > I want to access regression coefficients as variables for further analysis. replace coeff = _b[x] if obsset == `i' By default, Stata shows the end points of the confidence intervals in the regression tables, but there is also a nice user built command that lets us do an informative graph. >Wilhelmstrasse 36 >--- On Fri, 17/9/10, delibera@illinois.edu wrote: The solution. >*------------------- begin example ----------------- Re: st: save coefficients from a fixed effect regression In this guide we will cover how to make a coefficient plot with coefplot, and also how to make it show standardized regression coefficients. 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. mat beta=e (b) . If you are familiar with otherregression models that use maximum likelihood (e.g., logistic regression), you maynotice this iteration log behaves differently. bcoeff saves in a new variable regression coefficients (more generally, the b coefficient from a regression-like model) for each of several groups of observations. >predict u, u Coefficient Statistics. reg y x`i'' control1 control2, r (bcoeff supersedes deltaco by Zhiqiang Wang.) > Saves regression coefficients to a dataset or a data file. regression models) and then apply coefplot to these estimation sets to draw a plot displaying the point estimates and their confidence intervals. >Institut fuer Soziologie Fri, 17 Sep 2010 08:47:15 -0500 (CDT) However, I would then like to use these G's in a model where I regress some other variable, say z, on the estimated G's (and other stuff). I have run a regression and I would like to save the coefficients and the standard errors as variables. >* For searches and help try: st: Save coefficient p-value in matrix. The good news is that we can still find different regression components using asreg. When you wish to use the file in the future, you would just use the cd command to change to the c:regstata directory (or whatever you called it) and then use the elemapi file. Many folks would argue that we only want to standardize regression coefficients, and not indicators. >> know how to save the estimated coefficients from all the Datasets are available for subsequent use in the same session but are not saved as files unless explicitly saved prior to the end of the session. reg y x if obsset == `i' gen cons = 1 . > What I … 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.. > or something along those lines. With large data sets, I find that Stata tends to be far faster than SPSS, which is one of the many reasons I prefer it. Next by … forval i = 1/50 { Then, convert the matrix into a dataset (there is a command for that).
