![]() ![]() The sample command can also be used to select a specific number ofĬases. get file 'c:sset.sav'.Įxample 3: Selecting a specific number of cases The second means command will be run on the full data set. It will also terminate the temporary command, so that Temporary command will be in effect, and the descriptive statistics will reflect the reduced To illustrate this, we will issue the means command twice. In the example below, the means command is the procedure that will terminate the Temporary command allows you to create or transform variables and is in effect only until the next procedure isĮxecuted. The temporary command can be used with most SPSS commands,Īnd we will use it here to create a temporary subset of the data in the working file. The next example will illustrate how to take a subset without deleting the non-selected cases. In other words, the cases that are not selectedĪre deleted. Permanent sample of the data in the working file. The missing values designated by a "." (in the raw data file above) and has read them in as ![]() However, SPSS is letting the user know that it took Note that in the SPSS output there are a series of warnings messages. Variables ( iv1 and iv2) and two dependent variables ( dv1ĭv2). Will use the means command to show the effect of taking the subset. For this example, we will randomly select 20% of the data, and we However, in this situation, it may be best to take a random There are several ways that you could create a sub-sample, such as using the only the first 100 cases. Because the syntax may take hours to run, you may want to take a relatively small sample of your data and run the syntax on that to see if For example, suppose that you have a huge data file with thousands of cases, and that you written a syntax file to analyze theĭata. There may be times when you would like toĭata. The examples below will illustrate some of these methods. ![]()
