How to do a Logit Transformation in SPSS?

Hi there,

Need to do a logit transformation of a variable, so that I may test the assumptions for a Binary Logistic Regression test. Could someone please tell me how to do that? I know when transforming I need to input ‘Ln(p/1-p)’ in the compute variable screen, but I have no idea what ‘p’ is, or how to calculate it!

Any help much appreciated!

WHY this formula is different from the first one I have red on that website? (this below)


I can not explain that ”10” and ”20”… where do they came from ?
