Is there something similar to tabstatmat or makematrix for the table command? To report exponentiated coefficients (aka odds ratio in logisticregression, harzard ratio in the Cox model, incidence rate ratio, relative risk ratio),apply the eformoption. matrix C=A/s, A: a b and s a Stata scalar (see[P]scalar) or a literal number, returns C: a b containing the elements of A each divided by s. You can help adding them by using this form . /, meaning matrix division by scalar. * 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. exp must evaluate to a numeric result or missing. Storing results in a matrix. Lines 16 and 17 call the Mata … Many Stata commands store their results as scalars, macros, and matrices. The results of more than one VAR may be stored in a single .irf file, so we give the VAR a name, in this case var1. For example, after most estimation commands, parameter estimates are stored in a matrix e(b). Ian Watson's --tabout-- from SSC can be used to do this in a somewhat roundabout manner. It sounds confusing but it’s not. reg price mpg . Subtotal: $0.00. "MTAB: Stata module to store results in a matrix," Statistical Software Components S458858, Boston College Department of Economics. 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 … Third, I store the residual degrees of ... and cluster-robust standard errors. The mtab package consists of a collection of commands: mtab1, mtab2, msum, mest, mmat, mexcel, and mobs. 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. Later on, use can use that ‘codeword’ associated with the macro to make Stata blurt out the stored cell result. gsem is a very flexible command that allows us to fit very sophisticated models. After you run a command, you can see a list of the stored results by typing return list. The results from the single calls are collected in matrix e(_estadd_prvalue) (predictions) and matrix e(_estadd_prvalue_x) (x-values). sreturn list lists results stored in s(). does a simple solution to this problem exist? return scalar name = exp evaluates exp and stores the result in the scalar return(name). Notice: On April 23, 2014, Statalist moved from an email list to a forum, based at statalist.org. This will create numeric variables. sysuse auto . However, it is also useful in situations that involve simple models. sur les matrice commencent par matrix. tabstat income, stat (n mean sd) save. estpost command [ arguments] [, options] the various RePEc services. Stata tip 53: Where did my p-values go? You can also type ereturn list after an estimation command such as regress. Kit – Maarten Buis Aug 22 '14 at 12:54.

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. * 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. estadd prvalue post posts the collected predictions in e(b) so that they can be tabulated. We store results from the first regression in Stata memory under the name r1 and the title “Regression 1”. Examples of general commands that store results are: summarize, pairwise correlation (pwcorr), and confidence intervals (ci). This is the fifth post in the series Programming an estimation command in Stata. svmat can be used to create variables from the matrix. Subject 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. 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. Example: Note that the dashed lines appear as solid lines in Stata's results window: If you want them as a Stata matrix (why?) When requesting a correction, please mention this item's handle: RePEc:boc:bocode:s458858. Chunsen Wu, 2020. Examples of estimation commands are: regress, mixed, and logit. * instructs xml tab to combine all estimated results currently stored in memory into one table. mmat is a command of extracting the results from an existing matrix to a new matrix. (It seems that including brackets anywhere in … way that doesn't produce a huge number of irrelevant results 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. That was an incredibly helpful answer. Barbro asks For example, it stores a safe, temporary name in the local macro b that can be used for the matrix storing the point estimates. Handle: RePEc:boc:bocode:s458858 Note: This module should be installed from within Stata by typing "ssc install mtab".   Christopher Baum <> Date return list lists results stored in r(). 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. Besides storing calculations (known as scalars in Stata speak), Stata also stores words (called macros) and tables (matrices). Example: Note that eformalso transforms the standard errors (and confidence intervals),as is illustrated bellow: The example also illustrates that, … For technical questions regarding this item, or to correct its authors, title, abstract, bibliographic or download information, contact: (Christopher F Baum). re: st: Store results from table command in matrix The use of matrices might be scary for the beginner but there is no reason to fear.

Specify replace to drop results from previous calls. display "increment `increment'" System variables. GitHub Gist: instantly share code, notes, and snippets. i would like to save all results from these regressions so that i can later look at histograms of coefficients, standard errors, pvalues and the number of regressions the variables were included in. matrix b = e(b). 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 * http://www.stata.com/support/statalist/faq [Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] General contact details of provider: http://edirc.repec.org/data/debocus.html . mexcel is a command of exporting results from a matrix to an Excel file.   mtab1 is a command of making an one-way table and store the results (frequencies and percentages) in matrix. Remember the [row,column] numbers from … msum is a command of storing the results of mean, standard deviation, quantitles in matrix. This entry discusses using stored results. 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. For example, matrix VC=MYMAT*2.5 multiplies each element of MYMAT by 2.5 and stores the result in VC. Stata calls these returned results. No. Combining the commands can easily store the results in matrix The matrix with results can easily be further used to make tables in Excel or Word. matrix list e(b) . 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. It also allows you to accept potential citations to this item that we are uncertain about. However, An Introduction to Stata Programming | http://www.stata-press.com/books/isp.html Macros are little ‘codewords’ that represent another variable or string. Results of calculations are stored by many Stata commands so that they can be easily accessed and substituted into later commands. mobs is a command of showing and storing the results (number of repeated observations within specified variable categories) in matrix. mest is a command of exporting and storing the results (coefficient and confidence interval) in matrix. This allows to link your profile to this item. This allows the user, as well as other Stata commands, to easily make use of this information. As you can see from --return list--, the --table-- command does not save anything beyond the sample size. 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. Kit Baum | Boston College Economics & DIW Berlin | http://ideas.repec.org/e/pba1.html If you have authored this item and are not yet registered with RePEc, we encourage you to do it here. In Stata terms, this won't be a 2 x n matrix. You can pluck a cell of a matrix and store it as a macro. * For searches and help try: Please help - I do seem to have problems in phrasing the question in a You can help correct errors and omissions. tabout mpg rep78 using junk.csv, c(mean price) sum replace f(1) You may have to merge the resulting variables back with the original dataset if you want to have them both together. We just need to point the macro at the right matrix cell in order to extract the cell’s results. matrix first=e(first) estadd scalar APF=first[7,1] and that also doesn't work. 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. In the example below, I use the ttest command to test the null hypothesis that the mean weight is equal to 70.

You rather want a data set. Stata distinguishes several classes of elements, of which r(), e() and c()are most important. I would like to use the results from a "table" command as a matrix. -- example command Second, I allow the user to suppress the constant term. The main difference between esttab and estout isthat esttabproduces a fully formatted right away. matrix list e(V) To use the matrices later, we need to first store the matrices:. 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). Line 14 creates the temporary names for the results. All material on this site has been provided by the respective publishers and authors. Store stata tabulate results into a mata matrix.
