You rather want a data set. Is there something similar to tabstatmat or makematrix for the table command? estadd prvalue post posts the collected predictions in e(b) so that they can be tabulated. It collects results and posts them in an appropriate form in e().The basic syntax of estpost is:. (It seems that including brackets anywhere in … 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. Barbro asks You can pluck a cell of a matrix and store it as a macro. Specify replace to drop results from previous calls. From tabstat income, stat (n mean sd) save. 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. Many Stata commands store their results as scalars, macros, and matrices. General contact details of provider: http://edirc.repec.org/data/debocus.html . We store results from the ﬁrst regression in Stata memory under the name r1 and the title “Regression 1”. * instructs xml tab to combine all estimated results currently stored in memory into one table. For example, it stores a safe, temporary name in the local macro b that can be used for the matrix storing the point estimates. mtab1 is a command of making an one-way table and store the results (frequencies and percentages) in matrix. * 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. /, meaning matrix division by scalar. It sounds confusing but it’s not. Besides storing calculations (known as scalars in Stata speak), Stata also stores words (called macros) and tables (matrices). Store stata tabulate results into a mata matrix. 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. To Remember the [row,column] numbers from … display "increment `increment'" System variables. The use of matrices might be scary for the beginner but there is no reason to fear. matrix list e(b) . matrix b = e(b). mexcel is a command of exporting results from a matrix to an Excel file. However, it is also useful in situations that involve simple models. View cart ... tabulate oneway or tabulate twoway will save counts as a matrix. 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. Re: st: Store results from table command in 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. 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. Third, I store the residual degrees of ... and cluster-robust standard errors.

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). sreturn list lists results stored in s(). exp must evaluate to a numeric result or missing. * You can also type ereturn list after an estimation command such as regress. Lines 16 and 17 call the Mata … gsem is a very flexible command that allows us to fit very sophisticated models. We then store the results from the second regression under the name r2 and the title “Regression 2”. re: st: Store results from table command in matrix 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. To view the stored data after a general command you type “return list”. As you can see from --return list--, the --table-- command does not save anything beyond the sample size. return list lists results stored in r(). sur les matrice commencent par matrix. Ian Watson's --tabout-- from SSC can be used to do this in a somewhat roundabout manner. The results from the single calls are collected in matrix e(_estadd_prvalue) (predictions) and matrix e(_estadd_prvalue_x) (x-values).

"statalist@hsphsun2.harvard.edu" the various RePEc services. The matrix method. return scalar name = exp evaluates exp and stores the result in the scalar return(name). 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. http://fmwww.bc.edu/repec/bocode/m/mest.ado, http://fmwww.bc.edu/repec/bocode/m/mest.sthlp, http://fmwww.bc.edu/repec/bocode/m/mexcel.ado, http://fmwww.bc.edu/repec/bocode/m/mexcel.sthlp, http://fmwww.bc.edu/repec/bocode/m/mmat.ado, http://fmwww.bc.edu/repec/bocode/m/mmat.sthlp, http://fmwww.bc.edu/repec/bocode/m/mobs.ado, http://fmwww.bc.edu/repec/bocode/m/mobs.sthlp, http://fmwww.bc.edu/repec/bocode/m/msum.ado, http://fmwww.bc.edu/repec/bocode/m/msum.sthlp, http://fmwww.bc.edu/repec/bocode/m/mtab.sthlp, http://fmwww.bc.edu/repec/bocode/m/mtab1.ado, http://fmwww.bc.edu/repec/bocode/m/mtab1.sthlp, http://fmwww.bc.edu/repec/bocode/m/mtab2.ado, http://fmwww.bc.edu/repec/bocode/m/mtab2.sthlp, MTAB: Stata module to store results in a matrix. Kit 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. 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 … Please note that corrections may take a couple of weeks to filter through * http://www.stata.com/help.cgi?search sysuse auto The mtab package consists of a collection of commands: mtab1, mtab2, msum, mest, mmat, mexcel, and mobs. This is the fifth post in the series Programming an estimation command in Stata. In the example below, I use the ttest command to test the null hypothesis that the mean weight is equal to 70. No. An Introduction to Modern Econometrics Using Stata | http://www.stata-press.com/books/imeus.html The main difference between esttab and estout isthat esttabproduces a fully formatted right away. 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. For example, after most estimation commands, parameter estimates are stored in a matrix e(b). 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. We just need to point the macro at the right matrix cell in order to extract the cell’s results. Its syntax is much simpler thanthat of estout and, by default, it produces publication-style tablesthat display nicely in Stata's results window. That was an incredibly helpful answer. mmat is a command of extracting the results from an existing matrix to a new matrix. Stata distinguishes several classes of elements, of which r(), e() and c()are most important. Storing results in a matrix. See general information about how to correct material in RePEc. mtab2 is a command of making a two-way table and store the results (frequencies and percentages) in matrix. In Stata terms, this won't be a 2 x n matrix. Tue, 22 Nov 2011 10:52:22 -0500 We have no references for this item. re: st: Store results from table command in matrix mobs is a command of showing and storing the results (number of repeated observations within specified variable categories) in matrix. Later on, use can use that ‘codeword’ associated with the macro to make Stata blurt out the stored cell result. Example: Note that eformalso transforms the standard errors (and confidence intervals),as is illustrated bellow: The example also illustrates that, … Line 14 creates the temporary names for the results. * For searches and help try: I introduce the Stata matrix commands and matrix functions that I use in ado-commands that I discuss in upcoming posts. 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. However, To report exponentiated coefficients (aka odds ratio in logisticregression, harzard ratio in the Cox model, incidence rate ratio, relative risk ratio),apply the eformoption. This allows to link your profile to this item. $11,763.00. matrix list e(V) To use the matrices later, we need to first store the matrices:. 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. <> For example, matrix VC=MYMAT*2.5 multiplies each element of MYMAT by 2.5 and stores the result in VC. GitHub Gist: instantly share code, notes, and snippets. esttab is a wrapper for estout. This allows the user, as well as other Stata commands, to easily make use of this information. reg price mpg . insheet using junk.csv,clear tabout mpg rep78 using junk.csv, c(mean price) sum replace f(1) Option save() instructs xml tab to You can help correct errors and omissions.
