Dear all community, My issue is related to the R package (made4) that permits me to calculate the RV coefficient of co-inertia. However, it is a theoretical question. And if I am not mistaken, the list Usenet groups sci.stat.consult is not currently active. Let me explain briefly: Through different microbiota datasets, I have plotted PCoA, db-RDA and sPLS-DA using 3 different types of

I  could not find any distancecoefficient other than euclidean distace running for the data set. Are there any other coefficient works with negtive values.Also I cannot get summary out put (the eigen values) for PCO as for PCA.   Thanks. Dilshan [[alternative HTML version deleted]]

different F test in drop1 and anova
Hi, I was wondering why anova() and drop1() give different tail probabilities for F tests. I guess overdispersion is calculated differently in the following example, but why? Thanks for any advice, Tom For example: > x<-c(2,3,4,5,6) > y<-c(0,1,0,0,1) > b1<-glm(y~x,binomial) > b2<-glm(y~1,binomial) > drop1(b1,test="F") Single term deletions Model: y ~
