Hello Dears;

There are about 70 items and 30 cases in my research study in order to use in Factor Analysis in SPSS. There is an error: correlation matrix is not positive definite. What can I do about that?

I changed 5-point likert scale to 10-point likert scale. I increased the number of cases to 90. But did not work. Hope you have the suggestions.

Best regards;

Dashtpeyma
