https://archive.ics.uci.edu/ml/datasets/Liver+Disorders lists some papers which have used this dataset. I went to one, Turney, and it says:
The target concept was defined using the sixth column: Class 0 was defined as “drinks < 3” and class 1 was defined as “drinks ≥ 3” Column seven was originally used to split the data into training and testing sets.
In support of this, the file
- selector field used to split data into two sets.
This doesn't sound like a dependent variable.
But I went to another, Jiang and Zhou and it says there are 6 attributes (hence, presumably, the seventh is the one they use as the dependent variable).
I also found this which claims that the seventh variable is:
a dependent variable with two levels, indicating presence or absence of a liver disorder
Are a lot of people doing classification on a completely random variable?
