Yes, it is! Many datasets will have codebooks or documentation that explain which weight to use, such as this IPUMS user group question. Most likely, a survey dataset uses a probability weight, or pweight. a mean, works a bit differently, by using either a frequency weight or a probability weight.В See this guide to probability and frequency weights to understand the difference.

If you are using a survey dataset with weights, getting summary statistics, e.g. Your first concern is to make sure the data look as you expect them too.

Import delimited 'in_class_data.csv', clear firstrow indicates that the first row contains the variable names, which is also important.В The clear option clears out any data you already had open. Note the option sheet('Sheet1') indicates which sheet to use, because each Excel file can contain many sheets. Using the File > Import > Excel spreadsheet menu is a good way to figure out the command. Import excel 'in_class_data.xlsx', sheet('Sheet1') firstrow clear If it's an Excel file (xls or xlsx), try: The Stata file format has the file extension. Now, let's look at the data files we'll use for the workshop. Once you have the key, you can set it using You may need to get an API key from the FRED website. Import fred CPIAUCSL CPILFESL, daterange( ) aggregate(annual,avg) clear Click on Submit the data will import, and you'll see a command like this in the results window: You'll now have the opportunity to select the time period you want to cover, and the frequency (e.g. Select the first two results, click Add, and then Import.

It will capture your commands and your output. Change it to the folder where you have saved the data. You can change it with File > Change Working Directory. This is the first thing you should know, and a quick way to avoid problems. The log file can be turned on and off, but it is a good idea to help you keep track of what you've done. It could be /* like this */ for the middle of a line.ДЄ log file records the output of the commands as you run your code. Stata will ignore the text of the comments when you run your code, but they make your. do files along with their papers.ДЄ properly documented do file will contain comments that communicate your intentions at each step of code. the American Economic Review) require that authors submit. With a correctly written do file, anyone can reproduce your analysis. By using do files, log files, and comments, Stata provides a complete system for documenting your analysis in a way that is totally reproducible.Дo files are scripts for automating Stata commands.
