I want to use the iris dataset provided by scikit-learn for a paper. But I don't know what the standard for referencing datasets is. What citation should I use for this dataset in my paper? Should I reference scikit-learn? Ronald Fisher for having introduced the dataset? Edgar Anderson for having collected the data? All of the above?
I would cite both papers (Anderson, 1936; Fisher, 1936), but not
scikit-learn, as the dataset is simply bundled with the library, but is not unique to it (for example, the same
iris dataset is bundled with
R environment, as well). Having said that,
scikit-learn certainly has to be cited as well, if used, but not due to use of the dataset.
I think that citing Scikit-learn is sufficient. According to Scikit-Learn documentation you should cite their paper. You can always add a reference the Iris datset in Scikit-Learn by providing a link to the page.
