Dataset Card for Dataset Name
This dataset is a precise version of Statlog (German Credit Data), donated on 11/16/1994.
We used the following Python script to produce this Hugging Face dataset.

Note that there is another file for numerical data, but seems that the content is not more than what we have so far, so we don't include it.
