Collinearity spss
WebMay 23, 2024 · I am using SPSS to run linear regression with several predictors. In some cases, when I threw in some variables, SPSS will show the regression model with all the variables. But at the bottom, it also shows a table named "Excluded variables." I am not sure what it means. I suspect it may be a detection of multicollinearity involving these … WebTo do this in SPSS, ... The dependent variables should all be moderately related, but any correlation over .80 presents a concern for multicollinearity. Equality of covariance matrices is an assumption checked by running a Box’s M test. Unlike most tests, the Box’s M test tends to be very strict, and thus the level of significance is ...
