I believe the current section on the Wigner parabolic distribution must contain mistakes. The table and the text give two different formulas for the PDF and I believe both are incorrect. (Neither seems properly normalized, and the one in the text seems like an improperly normalized version of the semi-circular distribution. It would be nice with a citation to establish notability as well. If it is not corrected, I believe it is better to delete the section than leave it as it is.
