STATA forloops: foreach and forvalues - Duration: 5:01. junchen feng 39,793 views. forvalues On the other hand, looping over a list of evenly-spaced numbers is the specialty of forvalues , and it will do it faster than foreach . Also, since foreach has to construct the whole list of numbers before it can start, it can only handle relatively small lists.

The loop is executed zero or more times; it is executed zero times if the list is null or empty. Also see[P] forvalues, which is the fastest way to loop over consecutive values, such as looping over numbers from 1 to k. foreach lname in list {:::} allows a general list. Somebody asked how to count the number of occurrences of a string within a string. For example, if I have the following data, I want to generate new variables countSS, countSM, and countSG that contains the number of occurrences of “SS”, “SM”, or “SG” in variable awards. Mar 14, 2013 · Fortunately, Stata has a set of built-in tools to make this process easier. This article will show you how to use the -forvalues-command in Stata in order to automate repetitive tasks. Learning how to use this tool will help make your data analysis code cleaner, shorter, and faster to write.

Jul 23, 2015 · Stata have three commands for performing loops: foreach, forvalues and while. In this tip, I will teach you how to loop using foreach loop, which is perhaps the most common one. You will receive tips about forvalues and while loops soon. Aug 31, 2010 · -forvalues- and the other -use- syntax Posted on 31 August 2010 by Mitch Abdon -use-, which loads a Stata-format dataset (*.dta), is most likely the first command one learns in Stata. Forvalues is, arguably, the easiest loop to write. It will only count sequences of numbers, so the variable that you are calling must include numeric values. You can write out forvalues or use the shortened forval command. You will need to distinguish how you want to count through the number sequence. Somebody asked how to count the number of occurrences of a string within a string. For example, if I have the following data, I want to generate new variables countSS, countSM, and countSG that contains the number of occurrences of “SS”, “SM”, or “SG” in variable awards. How can I “fill down”/expand observations with respect to a time variable? | Stata FAQ A time series data set may have gaps and sometimes we may want to fill in the gaps so the time variable will be in consecutive order.

Stata has several ways of doing loops: foreach, forvalues and while. We don’t have the time to demonstrate all of them, so we will show you two examples of looping across variables. We don’t have the time to demonstrate all of them, so we will show you two examples of looping across variables. Stata has two built-in variables called _n and _N. _n is Stata notation for the current observation number. _n is 1 in the first observation, 2 in the second, 3 in the third, and so on. _N is Stata notation for the total number of observations. Let’s see how _n and _N work. Sep 25, 2013 · There is a new command in Stata 13, putexcel, that allows you to easily export matrices, expressions, and stored results to an Excel file. 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.

The Stata macro is really an alias which has both a name and a value: when its name is dereferenced, it returns its value.

Jun 16, 2012 · Stata is trying to do what you want it to, but you're making it generate a variable that already exists when it tries to run through each loop.

Jun 20, 2017 · This will go over the basic syntax and information about foreach and forvalues loops in Stata, as well as how to use them with levelsof. The initial foreach statement tells Stata that we want to cycle through the variables inc1 to inc12 using the statements that are surrounded by the curly braces. The first time we cycle through the statements, the value of var will be inc1 and the second time the value of var will be inc2 and so on until the final iteration where the value of ... Specifically, this dataset introduces looping over values with the “forvalues” command when exploring data in the early stages of a project. The dataset is a subset of data derived from the Wellcome Trust Monitor Survey 2009, and the example examines using loops to improve efficiency, accuracy, and clarity of work.
