Unable to perform complex many to many merge. History Stata was first released in January as a regression and data management package with 44 commands, written by Bill Gould and Sean Becketti.
The name Stata is a syllabic abbreviation of the words statistics and data. This window provides a preview of the data in your text file. The first step is to indicate whether the data matches a predefined format, which would be a format saved from a previous text file imported with the Text Import Wizard. This would be the case if you had already imported a text data file into SPSS in the past that was formatted exactly the same way, and had chosen to save the import format during the last step of the Text Import Wizard.
In most cases there will not be a predefined format. If your data matches a predefined format, click Yes and then browse for and upload the file that defines the format. If your data do not match a predefined format, click No , then click Next. If your data did not match a predefined format you will need to tell SPSS how your data is arranged, so that it understands where one column ends and the next begins.
For text files, there are two types of "arrangements": delimited and fixed width. If you are importing a CSV file, you have delimited data. You will also need to tell SPSS if the datafile contains variable names. For CSV files, variable names are typically included on the first line of the data file, before the data begins; however, some datafiles do not include variable names.
In the "How are your variables arranged" area, click the radio button that matches your data's format:. In the "Are variable names included at the top of your file" area, click Yes or No. We now need to tell SPSS what row our data begins on, and how many rows should be read.
For CSV files, the first row typically contains the variable names, and the data values begin on line 2. However, you can choose to skip over certain lines if necessary. One example where this occurs is in Qualtrics survey data output to CSV: The second row frequently contains variable labels, and oftentimes there may be a third row containing import IDs, and the data actually begins on line 4.
In the "Which delimiters appear between variables" area, select the check box that reflects the delimiter used in your data. The delimiter is what is used to separate values from each other within the data. If the text file is a. If you do not know which delimiter is used in the text file, refer to documentation that is associated with your data or ask someone who knows how the data file was created.
The options Remove leading spaces from string values and Removing trailing spaces from string values were added in SPSS version If you are using SPSS version 24 or earlier, you will not see these options on this window. SPSS attempts to guess what delimiters your file is using. Notice how that affects the parsing of variable Major :.
Because SPSS thinks that both spaces and commas were used as delimiters, it thinks that the spaces occurring in the names of the majors delimit observations for subsequent variables, and hence, SPSS interprets individual words as readings for the adjacent variable s here, variables Height , Weight , and Smoking.
Clearing the check box next to Space will correct this, and the change will be reflected in the preview. Notice, however, that there was still at least one case where the observation for Major was incorrectly split across two columns.
Notice how the value has double quotes " before the first word and after the last word. These quotes are being used as the text qualifiers; that is, they indicate where the observation starts and ends. To correct this, we need to change the text qualifier option to Double quote. This step allows you to specify the format for each variable in the data file. In the "Specifications for variable s selected in the data preview" area, SPSS explains what criteria it uses to "guess" what format to use.
In SPSS versions 24 and earlier, the default format chosen for a given variable is based on the values present in the first records. You can select any of the variable names columns in order to change the variable name or alter its format.
For example, in the example above we have selected the variable bday in the Data Preview area. It is important to check every variable to make sure the format and length is correct, rather than relying on SPSS to correctly identify the variable formats; this ensures that you control exactly how each variable was read.
In the final step, you can choose to save the file format that you just defined for the current data file in case you will import data with the same structure and format in the future.
Saving the syntax would allow you to format future data files in the same way without having to manually select each of the options in the Import Wizard again. A preview of your data appears at the bottom of the dialog box. If you are satisfied with the way the preview looks, click Finish to finalize the import.
