Hello, I'm A Poor Historian. I noticed that you added or changed content in an article, Taguchi loss function, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Thank you. ― A Poor Historian (talk) 14:24, 26 January 2019 (UTC)
