when you want to overwrite x), type replace x=invnorm(uniform()). To do (1), use command clear (see below).

In this case, you have three options: (1) clear the data, (2) remove variable x, or (3) or explicitly tell Stata to create a new variable with the same name (i.e. You are done with obs=50, so you change the number of observation to 100 ( set obs 100) and again type gen x=invnorm(uniform()), then you will get an error message. Suppose that you first set the number of observations to 50 and then create a variable called x by typing gen x=invnorm(uniform()). Note that, obviously, you cannot create a variable that has the same name as the existing variable. Here are some other commands and facts that you may need to know.įor example, to create a standard normal variable and call it x, Some basic commands that you use to do Problem set 2 are included in the questions. Log files are stored in the current directly. Since text log-files are just text files, you can read and print them using text editors (such as emacs in Unix or Notepad in Windows). Then you should make sure the log is closed and type In some cases, you may want to add more results to the existing log file. This command overwrites the existing log file. Stata does not automatically close the log, so if this happens, close the log first (you can check if the log is open by looking at the bottom of the Stata Results window – if it’s open, it says log on) and then type If you make a mistake in your do-file and receive an error message, Stata stops the procedures. Alternatively, you can start a log, then run your do-file that does not contain the log using. When you do so, it is safe to enter log using …, replace (see below). Of course, you can include these commands ( log using…and log close) in your do-file. When you are done with the analysis, type If you don’t add the extension, Stata creates smcl-style log files. You can read log-files written in smcl only in the viewer of Stata and smcl-style logs contain some annoying style, so I recommend that you use a text file version of log-file. There are two versions of log-files: one is Stata formatted (smcl) and another one is a text file. You can record all results that appear in the Results window in a log file. If you want to modify your do-file, type doedit filename. do is assumed when you enter do or doedit, so you don’t have to explicitly spell out your filename as do sample.do do sample is sufficient.

You can run the entire file by typingįilename can be any name. When you have finished typing your code, you can run it by selecting it and hitting the do button. You can change the location of the current directory by the cd command, as in cd temp, for example (assuming that you have already created a folder called temp in Data directory). You can find the location of the current directory at the bottom left hand corner of the window (something like C:\Data in Windows). Stata looks for data and do-files in the current directory and save new data files there. Here you should make sure it is saved in the current directly. When you finish entering commands, save the do-file.

To create a do-file, click on the do file button or type So we are just telling Stata what to do all in advance, instead of one by one. The way do-files work is very easy: we first create a file that contains all the commands that Stata should execute, and then tell Stata to execute them. If you don’t have a do-file when you want to repeat the same analysis again or modify your past analysis, you will have to type the same commands again. In addition, it is important to create do-files to keep track of what you did. This can be inconvenient once your commands become more elaborate. Without do-files, you have to type a command, wait for an execution, and then type another command. Do-files simply contain commands that you want Stata to execute. Problem sets usually require you to turn in your do-file. The Review window records your commands and the Variables window lists the variables in your data set (including the one that you created). You will type your commands in the Stata Command window.

Then four windows will appear on your monitor. If you use Stata for Unix, type at the athena command prompt: You just have to double-click on the wstata (or stata) icon. If you use Stata for Windows, starting Stata is straightforward.
