What is the use of the "case label" in SPSS19.0 linear regression?
First, the diagram, for example, you select ZRESID in Y, and dependent in X2, just to see the scatter diagram of the dependent variables and the normalized residuals, and see what the two are.
Also, if you select a variable in the case tag, such as the flow ratio, the value of the flow ratio will be given next to each point in the scatter plot.In general, case labels are not necessary, so the graphics can be too confusing.
The two are used in coordination. That is, if you do not choose to draw graphics, there is no need to select case labels.
