![]() ![]() Csv stands for "comma separated values" and are text files where the data matrix is described. Then it might be better to save the Excel data in a. ![]() However, when the dataset is large the copy and paste function might cause some problems. Then rename the variables one by one with the help of the rename command. ![]() If that happens, select everything but the names in Excel, and paste all the values into the data editor. Sometimes, however, there are some problems with the names, and Stata turns all variables into text. ![]() We can usually get the variable names as well, if there are any in the Excel document. If it is in Excel format I usually create an empty dataset (either by restarting Stata or by writing the command clear) and paste all the data into the data editor. We then write the command, the old name of the variable, and then the new name:Ī common situation when working with data is that we have data somewhere, but not in Stata format. If we want to change the name, for instance to "population", we can rename the variable with the rename command, usually abbreviated ren. New variables are automatically named "var1", "var2" and so on. In the QoG dataset, which I use in a lot of examples, the observations are countries, and the variables are country characteristics. If it's persons, each person should have its own row, and so on.Įach variable gets its own column. If it's countries, each country should have its own row. If we do, the variable must be a string variable, and the numbers will be treated like any other text, and cannot be analyzed statistically.Įach observation - what we're comparing - should have its own row in the dataset. If it is a number the variable becomes a numeric, and if it is a piece of text the variable turns into a "string variable", a text variable. The first value we enter determines the type of variable. Then we can just start to enter our data in the cells, or paste it, from Excel for instance. We just click the button "Data editor", the symbol with the pen. ![]()
