Besides storing calculations (known as scalars in Stata speak), Stata also stores words (called macros) and tables (matrices). In the example below, I use the ttest command to test the null hypothesis that the mean weight is equal to 70. msum is a command of storing the results of mean, standard deviation, quantitles in matrix. – Maarten Buis Aug 22 '14 at 12:54. For example, to get the N, mean, and standard deviation of personal income, enter: . The matrix method. Examples of general commands that store results are: summarize, pairwise correlation (pwcorr), and confidence intervals (ci). For example, when we want to compare parameters among two or more models, we usually use suest, which combines the estimation results under one parameter vector and creates a simultaneous covariance matrix of the robust type. matrix b = e(b). Ian Watson's --tabout-- from SSC can be used to do this in a somewhat roundabout manner. If your code has previously stored something in return(name), whether a scalar, matrix, or whatever else, the previous value is discarded and this result replaces it. It also allows you to accept potential citations to this item that we are uncertain about. Subject Stata distinguishes several classes of elements, of which r(), e() and c()are most important. reg price mpg . We store results from the first regression in Stata memory under the name r1 and the title “Regression 1”.

In fact, once you have grasped the use of matrices to store your results… I also tried writing a new _estadd_apf.ado subcommand and couldn't get that to work, and tried using the myel[#] syntax described in the estout help file and that does not work either. re: st: Store results from table command in matrix The results from the single calls are collected in matrix e(_estadd_prvalue) (predictions) and matrix e(_estadd_prvalue_x) (x-values). You can also type ereturn list after an estimation command such as regress. As you can see from --return list--, the --table-- command does not save anything beyond the sample size. However, it is also useful in situations that involve simple models. display "increment `increment'" System variables. The main difference between esttab and estout isthat esttabproduces a fully formatted right away.

From: Nick Cox Prev by Date: RE: st: psmatch2 with exact matching; Next by Date: st: Updating the value of a specific cll of a matrix using the value of a variable; Previous by thread: st: Store results from table command in matrix The mtab package consists of a collection of commands: mtab1, mtab2, msum, mest, mmat, mexcel, and mobs. This will create numeric variables. mmat is a command of extracting the results from an existing matrix to a new matrix. tabstat income, stat (n mean sd) save. In Stata, the .tabstat command computes aggregate statistics of variables such as mean and standard deviation, and its save option stores these statistics in a matrix. An Introduction to Stata Programming | http://www.stata-press.com/books/isp.html i have tried to to this with macros, but then thought it might be best to save the coefficients matrix, compute the standard errors and pvalues and save these as a matrix as well.   Its syntax is much simpler thanthat of estout and, by default, it produces publication-style tablesthat display nicely in Stata's results window. gsem is a very flexible command that allows us to fit very sophisticated models. tabout mpg rep78 using junk.csv, c(mean price) sum replace f(1) svmat can be used to create variables from the matrix. That was an incredibly helpful answer. Specify replace to drop results from previous calls. We have no references for this item. esttab is a wrapper for estout. * instructs xml tab to combine all estimated results currently stored in memory into one table. If you want them as a Stata matrix (why?)   To view the stored data after a general command you type “return list”. Kit Baum | Boston College Economics & DIW Berlin | http://ideas.repec.org/e/pba1.html However, Barbro asks You can pluck a cell of a matrix and store it as a macro. Later on, use can use that ‘codeword’ associated with the macro to make Stata blurt out the stored cell result. Re: st: Store results from table command in matrix. Examples of estimation commands are: regress, mixed, and logit. mexcel is a command of exporting results from a matrix to an Excel file. From Basic syntax and usage. After you run a command, you can see a list of the stored results by typing return list. "statalist@hsphsun2.harvard.edu" I recommend that you start at the beginning. This allows the user, as well as other Stata commands, to easily make use of this information. Thus, the procedure forreporting certain additional statistics is to add them to thethe e()-returns and then tabulate them using estout or esttab.The estadd command is designed to support this procedure.It may be used to add user-provided scalars and matrices to e()and has also various bulti-in functions to add, say, beta coefficients ordescriptive statistics of the regressors and the dependent variable (see the help file for a … .table var1 var2 , c(mean var3) concise To list the matrices of stored results, we can. exp must evaluate to a numeric result or missing. mobs is a command of showing and storing the results (number of repeated observations within specified variable categories) in matrix. way that doesn't produce a huge number of irrelevant results You can help correct errors and omissions. If you know of missing items citing this one, you can help us creating those links by adding the relevant references in the same way as above, for each refering item. Macros are little ‘codewords’ that represent another variable or string. To report exponentiated coefficients (aka odds ratio in logisticregression, harzard ratio in the Cox model, incidence rate ratio, relative risk ratio),apply the eformoption.
