Hi List. It may be a very simple question, but I couldn’t find an answer on the internet. Which function (maybe in a specific package) would I use to perform a Cochran C Test for Homogeneity of Variances? Stats package have the mantelhaen.test, but I’m “almost sure” that It’s not what I want, it’s probably the Cochran Q Test. So, any ideas? Thank you for the pacience. ------------------------------------------------------------- MSc. <mailto:r.aluizio@gmail.com> Rodrigo Aluizio Centro de Estudos do Mar/UFPR Laboratório de Micropaleontologia [[alternative HTML version deleted]]
