If you are using the menu system to run CORRELATIONS (Analyze->Correlate->Bivariate), then both the descriptive statistics and listwise deletion are requested by clicking the Option button in the main Correlations dialog and choosing those features in the Options dialog. You can see whether the dependent variable still has a non-zero standard deviation, i.e., is not constant, under these conditions. By specifying listwise deletion of missing values, the correlations descriptive statistics for all variables will be calculated from the cases that Regression will use by default. The following command requests the correlations between all pairs of these variables, as well as descriptive statistics.
if the explanatory variable changes then it affects the response variable. The independent variable is called the Explanatory variable (or better known as the predictor) - the variable which influences or predicts the values. Suppose that your dependent variable is called Y, your predictors are X1, X2, and X3, and that you had a WLS weight variable called WT. In regression the dependent variable is known as the response variable or in simpler terms the regressed variable. It is therefore fairly important to check the descriptive statistics of the regression variables for the cases that are actually used in the regression analysis. By default, Linear Regression omits cases from the analysis that are missing on any of the variables listed in the regression analysis, whether dependent, predictors, selection variables, or WLS weights. Listwise deletion of missing values can also result in a constant dependent variable. This has been corrected in SPSS Statistics 17.0.1.Ī constant dependent variable can result from filtering your cases based on the dependent variable to include just 1 value. The wording about 'the dependent variable has been deleted' is a defect and has been reported to SPSS Development. The message is incorrect the dependent has not been deleted, but is a constant. I am new to Multivariate linear regression analysis.This will occur if your dependent variable is a constant. Why is Type III Sum of Squares error 1171.320 for age, education and income?Ĥ. Which method(Pillai's Trace, Wilks' Lambda, Hotelling's Trace, Roy's Largest Root) should be used for a case like mine?ģ.
Am I approaching the problem in a proper way? I mean am I doing the right analysis in SPSS?Ģ. However, it still can’t deal with alphanumerics in frequency tables, giving us a strange message about invalid float.

I am using a sample of 400 people with age, income, education as dependent variables and having health insurance as independent variable.
Statplus regression wont pick up dependent variable free#
I am trying to determine the reason why(and how many) people with health insurance do not fully use all of its benefits(like free flu vaccines).
