As can be observed, testing of hypothesis based on the main effects for thisdesign model can be performed using Hotelling's T 2 test. Simultaneous confidence intervalsare also proposed. Finally, the proposed methodology is applied to a real-life example. 2013 artículo científico 0188-6266 https://www.redalyc.org/articulo.oa?id=41628339002 en http://www.redalyc.org/revista.oa?id=416 Acta Universitaria application/pdf Universidad de Guanajuato Acta Universitaria (México) Num.3 Vol.23 |
