Re: [R] Chi-square test: Specifying expected proportions for two way table

2021-10-16 Thread Bert Gunter
Perhaps I misunderstand, but ?chisq.test explicitly says: "If x is a matrix with at least two rows and columns, it is taken as a two-dimensional contingency table: the entries of x must be non-negative integers. Otherwise, x and y must be vectors or factors of the same length; cases with missing v

2021-10-16 Thread Miloš Žarković
Hi, Is there a function where I can specify expected proportions for the two-way table to calculate the Chi-square test? chisq.test allows specifying only the one-way table. Otherwise, I will have to write the function, but I never trust myself not to make a mess programing. Thanks, Miloš Miloš

Dear Sergio, You appear to have asked this question twice on r-help. Anova() has no specific method for “gls” models (I assume, though you don’t say so, that the model is fit by gls() in the nlme package), but the default method works and provides Wald chi-square tests for terms in the model. I

Dear all, Anova() for .car package retrieves Chi-square statistics when I'm testing a model the significance of a multivariate .gls model gls(x~1+2+3+x,corBrownian(phy=tree), ...). Is this Chi-square a two-sided test? Thank you. Best, Sérgio. [[alternative HTML version deleted]]
