Even stronger and farther-reaching a symbol of Paris than the Eiffel Tower, the Notre-Dame-de-Paris cathedral is now burning down. Only Hugo can make for the memory of this monumental loss: “Sur la face de cette vieille reine de nos cathédrales, à côté d’une ride on trouve toujours une cicatrice. Tempua edax, homo edacior; ce que je traduirais volontiers ainsi: le temps est aveugle, l’homme est stupide.” Victor Hugo, Notre-Dame-de-Paris, 1831 “Notre-Dame est aujourd’hui déserte, inanimée, morte.

Among the many papers published in this special issue of TAS on statistical significance or lack thereof, there is a paper I had already read before (besides ours!), namely the paper by Jonty Rougier (U of Bristol, hence the picture) on connecting p-values, likelihood ratio, and Bayes factors. Jonty starts from the notion that the p-value is induced by a transform, summary, statistic of the sample, t(x), the larger this t(x), the less likely the null hypothesis, with density f⁰(x), to create an embedding model by exponential tilting, namely the exponential family with dominating measure f⁰, and natural statistic, t(x), [...]
