Se hela listan på spss-tutorials.com Running a basic multiple regression analysis in SPSS is simple. For a thorough analysis, however, we want to make sure we satisfy the main assumptions, which are. linearity: each predictor has a linear relation with our outcome variable; normality: the prediction errors are normally distributed in the population; homoscedasticity: the variance of Regression models are just a subset of the General Linear Model, so you can use GLM procedures to run regressions. It is what I usually use. But in SPSS there are options available in the GLM and Regression procedures that aren’t available in the other.

SPSS. To do this, CLICK on the Analyze file menu, SELECT Regression and then Linear. If the relationship is not linear, OLS regression may not be the ideal tool for the analysis, or modifications to the variables/analysis may be required.

An unusual (but much stronger) approach is to fit a variety of non linear regression models for each predictor separately. Doing so requires very little effort and often reveils non linearity.

12. Help with Linear Regression SPSS. Once you have completed the correlation of your data, you can use linear regression to predict one variable’s value based on another variable’s value. While linear regression SPSS methods aren’t something you can simply jump right in to, if you have the assistance of an expert, it’s not that difficult. Figure 1: Linear regression.
