The Generalized Estimating Equations procedure extends the generalized linear model to allow for analysis of repeated measurements or other correlated observations, such as clustered data Mit den relativ neuen GEE-Modellen (Generalized Estimating Equations) können Daten mit kor-relierten Residuen (z.B.

Use of the estrogen patch reduces the depression score by 4 points. There is also an effect for the estrogen patch when controlling for pretest depression and visit. The final interpretation of these results indicate that there is a significant effect for the pretest, i.e., for every one point increase in the pretest score there is about a 0.4 increase in the depression score, when controlling for treatment and visit. If you run the estimated marginal means for the model you will. As such, if the main effect or interaction has a 1 in it your beta will be zero. So SPSS chose 1 as your reference group for everything. All of the betas are part of a regression equation, however because you are using binary data the program cannot solve it without a reference group. We have a video tutorial that covers this same material in slightly more detail.Home GEE SPSS output interpretation Spss Statistics - Spss Statistics Near Mįirst, for some reason instead of decimal places your output has commas, not sure why that is happening but you can still interpret it. You should now have a good idea of how to import data from Excel into the SPSS statistics package. It also got level of measurement correct (see the Measure column), identifying SubjectID, Gender, Education and DogOwner as nominal data, and FrisbeeThrowing as scale (that is, as interval/ratio data). Variable ViewĪs you can see from the image below, SPSS did a good job with our sample data, correctly identifying SubjectID, Gender, DogOwner and FrisbeeThrowing as data type numeric, and Education as data type string. This will bring up the variable view within SPSS. To check this, click on the Variable View tab (see red arrow, above). Is numerical data correctly set as numerical, for example? If everything looks okay, the next stage is to check whether the various data parameters have been set correctly. Obviously, the first thing to do here is to check that the data has come across successfully. SPSS will import your data into a new Data View with variable names at the top. Once you’ve selected the options you require, and checked your data looks okay in the preview window, press OK to begin the import. If SPSS is unable to determine a data type on this basis it will assign the variable to a string type. In our example, a variable will be assigned to a particular data type if 95% of values match that type (for example, if 95% of values are numeric in form). The percentage is the proportion of values in a particular column that must match a specific data type for SPSS to assign that data type to a variable.
This is how the latest version of SPSS assigns a data type to your variables. Mainly these are self-explanatory, but it is probably worth explaining the “Percentage of values that determine data type” option. This dialog box offers a number of options. Open the file, and you’ll get the Read Excel File dialog box. Then navigate to the folder that contains your Excel file, and you’ll see your Excel file pop up (see 2 above). In the Files of type box, you need to select Excel (see 1 above, though obviously things will look slightly different if you’re using a Mac). Once you click Data, the Open Data box will appear. To start, click File -> Open -> Data (as below). We’re going to use a method that allows backward compatibility with older versions of SPSS. There are a number of different ways to import data into SPSS.
Once you have got your worksheet straight, you can open up SPSS. For example, if you had coded one of the Frisbee Throwing Distance items as “50m” rather than just “50”, this would be a good time to make a correction. Our worksheet satisfies both these requirements. You can see in our example that we have 5 columns of data.īefore you begin the process of importing your data into SPSS, you need to ensure that your variable names are in the first row of the worksheet, and that there is no gap between the first and second rows. Open the Excel spreadsheet from which you wish to import data. This tutorial explains how to import data from Excel into the SPSS statistics package.
