I have a table in a database where each record includes the ID of a person and the ID of a property of that person. Each person may have more than one property. Which is the statistical instrument that let me measure the correlation between two properties?
E.g., Assume that we have the following DB table
IDPerson IDProperty
Pluto dog
Pluto disney
DonaldDuck duck
DonaldDuck disney
Huey duck
Huey disney
Dewey duck
Louie disney
Louie duck
I see a correlation between "disney" and "duck".
