These are useful features when studying the correlation between variables with mixed types. Particular emphasis is paid to the proper evaluation of statistical significance of correlations and to the interpreta
on all SPSS versions. A disadvantage, as we saw, is that it requires applying variable and value labels to the new variable. We'll therefore propose a faster approach that circumvents this. This will, however, require SPSS version 14 or higher with the SPSS Python Essentials properly ...

For categorical variable, each level is considered as an independent variable and is recognized by factor function. On the other hand, the numerical independent variable is either continuous or discrete in nature. Check out the Example given below for linear regression model summary to understand ...
