Relations between nominal variables ?

Postby VincentM » Mon May 09, 2016 1:35 pm


Currently I am studying a dataset with around 35.000 unique units, each with three variables X1, X2, X3. Each of these variables consist of 6 possibilities, which are nominal.
X1, X2, and X3 are different purchases that are labeled as a category name, 6 to be precise.

I would like to map the road customers make, from their first purchase to their third purchase.

On top of that, I would like to investigate whether a first purchase influences a second purchase, and whether a second purchase influences a third purchase.

This question is asked because I cannot find appropriate information on the relation between nominal variables.

Below I will show you what the sheet looks like.

customer ID x1 x2 x3
1 Chair Sofa Chair
2 Closet Wardrobe Sofa
3 Cabin Curtains Chair

Thanks in advance!

With kind regards,

Vincent M.
