*Best of the Best vs. Worst of the Worst.<\/p>\n\n\n\n

Rather than measuring total production, we take the\u00a0a few of the best<\/strong>\u00a0parts and the\u00a0a few of the worst<\/strong>, and we look for what sets them apart.<\/p>\n\n\n\n

The key is efficiency: by exaggerating the contrast, we highlight the important elements using very few parts.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

We are forming pairs<\/strong> BOB \/ WOW, and for each one, we enter the variables<\/strong> to compare, quantitative<\/strong> or qualitative<\/strong>. Ellistat provides a p-value<\/strong> and a conclusion<\/strong> : Does this variable distinguish between the good and the bad?<\/p>\n\n\n\n

\n

\ud83d\udca1 Method of roughing<\/strong>, to be used at the beginning of an investigation when it is not yet clear where to look. It identifies suspects; it does not establish causality. Once the factors have been identified, a design of experiments confirms and quantifies them.<\/p>\n\n\n\n

\u26a0\ufe0f Selecting outliers creates a deliberate bias: the differences observed in the variables are amplified<\/strong> compared to normal production. Do not directly apply the same ranges.<\/p>\n<\/blockquote>","protected":false},"featured_media":0,"menu_order":60,"template":"","meta":{"_acf_changed":true},"menu-guide-dutilisateur":[23],"class_list":["post-4592","guide-dutilisateur","type-guide-dutilisateur","status-publish","hentry","menu-guide-dutilisateur-5-statistiques-inferentielles"],"acf":[],"yoast_head":"\nBoB vs WoW -
