I already have an id variable, and I have multiple observations per id, but I want a new id variable containing 1 for the first id, 2 for the second, and so on. About the Stata statistical software Stata is an integrated package with a point-and-click interface and a command syntax. The latter is part of the Ado scripting language, which allows for extensive programmability of new features, as well as automation of repetitive tasks. In addition, Stata offers Mata. Stata’s official commands do not give much support to multiple response variables, although we gave an example earlier of the application of tabstat. One general strategy is to use an egen function to calculate something, (possibly) egen, tag() to tag just one observation in each of several groups, and then list to show My previous post discussed p-values in SPSS and Stata for probability-weighted data. This post provides more information on weighting in the base module of SPSS.

Then we format the database for stata with the code: xtset idcode year. Then we generate some quadratic variables. gen age2 = age^2 gen tenure2 = tenure^2. We regress our model of the form of: xtreg ln_wage age* ttl_exp tenure* south, fe 2016-07-13 2020-07-11 le 22/03/2006 20:10, Rudy Fichtenbaum a ecrit : > Stata Users: > > I am still learning my way around Stata after many years of using SAS. > In SAS it is fairly easy to write a program to do a simple Monte Carlo > study to illustrate the properties of least squares estimators. > > Is there anyone that has a simple example of a Monte Carlo Study for OLS? > > Thanks, > > Rudy > * > * For searches It is available for Windows, Mac and Unix systems.

mdev(exp) (allows by varlist:) (Stata interprets _N to mean the total number of observations in the by-group and _n to be the observation number within the by-group.) Having created the new variable dup, you could then . tabulate dup to see a report of the duplicate count. To base the duplicate count solely on name, type _n is the Stata way of referring to the observation number.

Combining putexcel with a Stata command’s stored results allows you to create the table displayed in your Stata Results window in an Excel file. Read more… Stata orders the data according to varlist1 and varlist2, but the stata_cmd only acts upon the values in varlist1. This is a handy way to make sure that your ordering involves multiple variables, but Stata will only perform the command on the first set of variables.

The state of an RNG corresponds to a spot in the sequence. The mapping is not one to one because there are more states than seeds. If you want to pick up where you left off in the sequence, you need to restore the state, as in the example below. Re: st: tag by category. Thank you very much!
