If a command is followed by a variable list or varlist (i.e.
Stata normally has exactly one data set in memory, and commands act on that data set. Some commands have subcommands, like label variable and label value. Most commands can be abbreviated, the exception being those that can destroy data (thus use, gen, replace, sum, reg). A Stata command is usually a verb, like use, generate, replace, summarize, or regress. The key to using Stata effectively is understanding its fundamental syntax, which applies to the vast majority of Stata commands.

If not, we'll talk about how to do all this in Reading in Data and you can get the example files then. If you are comfortable doing so, create a folder for the example files, make that Stata's working directory, and run the command above. This will put the example files in your current working directory. If this fails on your computer, try net get dws, from(). The example files for this class can be obtained within Stata by running:
Data wrangling is not something you read and understand-it's a skill you must practice.ĭata Wrangling in Stata includes the following sections: Do the exercises (some of them are straightforward applications of what you just learned others will require more creativity). This will help you retain more, and ensure you get all the details right-Stata is always happy to tell you when you're wrong.

Open Stata, and type in and run the example code yourself. To get the most out of Data Wrangling in Stata you need to be an active participant. We'll start by very briefly reviewing some basic Stata concepts that should be familiar to you, but if they're not, Introduction to Stata will do a much better job of teaching them to you. If you're new to Stata, we recommend working through our Introduction to Stata before proceeding. You'll learn a lot about Stata from this workshop, but the primary focus is on the tasks you'll need to carry out. Most data sets need to be transformed in some way before they can be analyzed, a process that's come to be known as "data wrangling." Data Wrangling in Stata will introduce you to the key concepts, tools, and skills of data wrangling, implementing them in Stata.
