SUMMARY
The formula for covariance presented in the discussion is incorrect. Specifically, the term y_bar should be replaced with (y - y_bar) in the calculation of chi-squared. This error is corroborated by its presence on the 8th slide of the referenced seminar PDF from the University of Geneva. The slide, despite numbering issues, accurately reflects the correct formula for covariance.
