Luminosity ()-stretch () relation for relativistic type IcBL SNe [42]. For all filters from , and combinations thereof, GRB-SNe are shown in blue, and the two known relativistic type IcBL SNe (2009bb and 2012ap) are shown in red. A bootstrap analysis was performed to fit a straight line to the dataset to find the slope () and -intercept (), which used Monte-Carlo sampling and simulations. The best-fitting values are and . The correlation coefficient is , and the two-point probability of a chance correlation is . This shows that the relationship is statistically significant at the 0.001 significance level.
