Use the following steps to perform linear regression and subsequently obtain the predicted values and residuals for the regression model.

The column of estimates (coefficients or parameter estimates, from here on labeled coefficients) provides the values for b0, b1, b2, b3 and b4 for this equation. For this example we will use the built-in Stata dataset called auto. Ideally, I want STATA to extract coefficients of mpg from each result and compile them into one independent file(any file is OK, .dta would be great).By doing this, I want to see the trend of coefficient of `mpg` as `weight` increases. st: save coefficients from a fixed effect regression. Next, we want to add some things to the table, like R-squared, residual degrees of freedom and BIC. Fortunately, with modern software like Stata it is pretty easy both to automate the distinction between indicators and continuous variables, and to rescale and re-run models. Further, it reports the regression coefficients of the first stage regression when option first is used with the option fmb. That's the stuff to add indicated by a comment above. In this case, it would be easier to use Stataâs matrix language: First put x = (mean of gender, mean of age, mean of value) in a vector: . In R, SAS, and Displayr, the coefficients appear in the column called Estimate, in Stata the column is labeled as Coefficient, in SPSS it is called simply B. The output may also look a little different in different versions of Stata. Estimation commands store their results in the so-called e() returns (type ereturn list after running an estimation command to see a list of what has been stored).

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.

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).

(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.

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..

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).

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.
