The absolute values of Y vary so much that a normal linear regression is useless

Did you try any other transformation toward the linear? for example sign*log(abs(x))

If there were no negative values, I could use a logistic regression,

For ordinal DV you should use the ordinal regression

But I assume a better transformation may be better ...

Hi Anders

When you transform to -1,0,1 you lose some data.

Did you try any other transformation toward the linear? for example sign*log(abs(x))

Logistic regression is for non-ordinal categorical DV.

For ordinal DV you should use the ordinal regression

. How can I go about in order to do a statistical test for this?

otherwise we are referred to guessing. So hat is your research

question? What are these X and Y variables, and how were they

measured?

In addition, is it true that your sample size is about 30?

With kind regards
