To report exponentiated coefficients (aka odds ratio in logisticregression, harzard ratio in the Cox model, incidence rate ratio, relative risk ratio),apply the eformoption. To list the matrices of stored results, we can. However, In addition to the output in the shown in the results window, many of Stata’s commands store information about the command and it’s results in memory. I discussed this usage in the section Using temporary names for global objects in Programming an estimation command in Stata: A first ado-command using Mata. This entry discusses using stored results. You can pluck a cell of a matrix and store it as a macro. Storing results in a matrix. 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. 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 … Stata tip 53: Where did my p-values go? You can also type ereturn list after an estimation command such as regress. Store stata tabulate results into a mata matrix. It sounds confusing but it’s not. 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. Its syntax is much simpler thanthat of estout and, by default, it produces publication-style tablesthat display nicely in Stata's results window. You can help correct errors and omissions. View cart ... tabulate oneway or tabulate twoway will save counts as a matrix. "statalist@hsphsun2.harvard.edu" I recommend that you start at the beginning. reg price mpg . mest is a command of exporting and storing the results (coefficient and confidence interval) in matrix. Line 14 creates the temporary names for the results. Stata calls these returned results. However, it is also useful in situations that involve simple models. Examples of general commands that store results are: summarize, pairwise correlation (pwcorr), and confidence intervals (ci). The matrix method. It also allows you to accept potential citations to this item that we are uncertain about. Kit esttab and estout tabulate the e()-returns of a command, but not all commands return their results in e().estpost is a tool make results from some of the most popular of these non-"e-class" commands available for tabulation. Remember the [row,column] numbers from … For example, matrix VC=MYMAT*2.5 multiplies each element of MYMAT by 2.5 and stores the result in VC. .table var1 var2 , c(mean var3) concise The basic syntax of esttabis: The procedure is to first store a number of models and then applyesttab to these stored estimation sets to compose a regressiontable. mmat is a command of extracting the results from an existing matrix to a new matrix. In the Stata output that follows, ... irf create creates an .irf file that stores numerous results from the VAR that may be of interest in postestimation. Note that values not appearing in the two-way table show up as missings, so you might want to mvencode them as zeros (or not). Macros are little ‘codewords’ that represent another variable or string. Later on, use can use that ‘codeword’ associated with the macro to make Stata blurt out the stored cell result. 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. Christopher Baum Handle: RePEc:boc:bocode:s458858 Note: This module should be installed from within Stata by typing "ssc install mtab". way that doesn't produce a huge number of irrelevant results This is the fifth post in the series Programming an estimation command in Stata. sysuse auto . gsem is a very flexible command that allows us to fit very sophisticated models. return scalar name = exp evaluates exp and stores the result in the scalar return(name). matrix list e(V) To use the matrices later, we need to first store the matrices:. The main difference between esttab and estout isthat esttabproduces a fully formatted right away. No. Example: Note that the dashed lines appear as solid lines in Stata's results window: mtab2 is a command of making a two-way table and store the results (frequencies and percentages) in matrix. An Introduction to Stata Programming | http://www.stata-press.com/books/isp.html 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. [Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Basic syntax and usage. Third, I store the residual degrees of ... and cluster-robust standard errors. This allows the user, as well as other Stata commands, to easily make use of this information. "MTAB: Stata module to store results in a matrix," Statistical Software Components S458858, Boston College Department of Economics. matrix first=e(first) estadd scalar APF=first[7,1] and that also doesn't work. In the example below, I use the ttest command to test the null hypothesis that the mean weight is equal to 70. Use the collapse command. estadd prvalue post posts the collected predictions in e(b) so that they can be tabulated. * http://www.ats.ucla.edu/stat/stata/, http://www.stata-press.com/books/isp.html, http://www.stata-press.com/books/imeus.html, http://www.stata.com/support/statalist/faq, Re: st: Store results from table command in matrix, st: Updating the value of a specific cll of a matrix using the value of a variable, st: Store results from table command in matrix. – Maarten Buis Aug 22 '14 at 12:54. exp must evaluate to a numeric result or missing. For example, it stores a safe, temporary name in the local macro b that can be used for the matrix storing the point estimates. Examples of estimation commands are: regress, mixed, and logit. It collects results and posts them in an appropriate form in e().The basic syntax of estpost is:. estpost command [ arguments] [, options] Besides storing calculations (known as scalars in Stata speak), Stata also stores words (called macros) and tables (matrices). local increment = b[1,1]. The mtab package consists of a collection of commands: mtab1, mtab2, msum, mest, mmat, mexcel, and mobs. esttab is a wrapper for estout. If you are a registered author of this item, you may also want to check the "citations" tab in your RePEc Author Service profile, as there may be some citations waiting for confirmation. General contact details of provider: http://edirc.repec.org/data/debocus.html . I introduce the Stata matrix commands and matrix functions that I use in ado-commands that I discuss in upcoming posts. Barbro asks re: st: Store results from table command in matrix <> Specify replace to drop results from previous calls. Subject destring v*, force replace display "increment `increment'" System variables. All material on this site has been provided by the respective publishers and authors. ereturn list lists results stored in e(). Example: Note that eformalso transforms the standard errors (and confidence intervals),as is illustrated bellow: The example also illustrates that, … An Introduction to Modern Econometrics Using Stata | http://www.stata-press.com/books/imeus.html Re: st: Store results from table command in matrix. From We then store the results from the second regression under the name r2 and the title “Regression 2”. Many Stata commands store their results as scalars, macros, and matrices. Second, I allow the user to suppress the constant term. Date Results that are included in the e()-returns for the models can betabulated by estout or esttab. For technical questions regarding this item, or to correct its authors, title, abstract, bibliographic or download information, contact: (Christopher F Baum). As you can see from --return list--, the --table-- command does not save anything beyond the sample size. * instructs xml tab to combine all estimated results currently stored in memory into one table. sreturn list lists results stored in s(). When requesting a correction, please mention this item's handle: RePEc:boc:bocode:s458858. After you run a command, you can see a list of the stored results by typing return list.

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. sysuse auto If you use statsby with the saving() option it will not overwrite your current data set, but store the results in a separate file specified inside the saving() option. Ian Watson's --tabout-- from SSC can be used to do this in a somewhat roundabout manner. Results of calculations are stored by many Stata commands so that they can be easily accessed and substituted into later commands.
