Re: [R-sig-phylo] mixed phylogenetic model in MCMCglmm
Hi, thank you for your attention. My data consists of 1820 observations (species) grouped in 11 levels (I know that it is a lot!). I mean "crazy" estimates because if I run the models separately for each level (i.e. trimmed the database at each level), there is a very strong positive relationship between x and y. However, when running the full model, the slopes and intercepts are very different (e.g. negative or null slopes).

[R-sig-phylo] mixed phylogenetic model in MCMCglmm
I'm trying to run a mixed phylogenetic model using the function in the MCMCglmm R package of the same name. In this model, I want to estimate slopes and intercepts for each level of a given variable (modeled as a random effect). I tried to run the model with the following code. However, the estimates of slopes and intercepts for the random effect are crazy! (i.e. when running separate models for each level, the results are reasonable) There is something wrong with my code? (in the syntax of the model, or likely in the prior specification) prior<- list(G=list(G1=list(V=1, nu=0.002), G2=list(V=diag(2), nu=2, alpha.mu= rep(0,2), alpha.V=diag(1000,2,2))), R=list(V=1, nu=0.002)) model<-MCMCglmm(y~x, random=~phylo + us(1+x):group,family="gaussian",ginverse=list(phylo=inv.phylo$Ainv),prior=prior,data=data,nitt=nitt,burnin=burn,thin=thin, pr=TRUE) Cheers p.s the same model, but in the syntax used by brms has the form: model <- brm(y ~ x +(1|phylo)+(1+x|group), cov_ranef = list(phylo = A)...

[R-sig-phylo] Phylogenetic varying slopes and intercepts model
Hi, everybody I’m trying to fit a phylogenetic model to model the relationship between x and y (eg. lmer syntax: y~x +(1|species), species with their respective var-covar matrix). Given that species are grouped into major categories (families, orders, etc), What is the correct way to account for this hierarchical structure, while estimating slopes and random intercepts for one of those categories? For example, if I want the estimates of slopes and intercepts for each level of the family category: what is the correct way? a) y~x+(1|species)+(1+x|family), ## varying intercept-slope by family (family added as another random effect), b) y~x+(1+x|family/species) ## varying intercept-slope by family, accounting for the fact that species are grouped into family, or simply I have to add the family category as a fixed effect: c) y~x+family+(1+family|species) Best, -- Oscar [[alternative HTML version deleted]] ___ R-sig-phylo mailing list - R-sig-phylo@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-phylo Searchable archive at http://www.mail-archive.com/r-sig-phylo@r-project.org/

Re: [R-sig-phylo] PGLS with discrete binary independent variable?
your question can be evaluated using generalised linear mixed models (GLMM). For this, a excellent R alternative is MCMCglmm program, developed by Hadfield (2010). Chers Hadfield JD (2010). MCMC methods for Multi-response Generalised Linear Mixed Models: The MCMCglmm R Package. Journal of Statistical Software, 33(2), 1-22. 2014-11-13 15:03 GMT-03:00 Brian A. Gill gillbri...@gmail.com: Dear list members. I am working on a comparative phylogenetic analysis. My independent variable is latitude (discrete binary; Colorado or Ecuador) and my dependent variable is elevation range breadth in meters (continuous). It seems that independent contrasts are not appropriate because they require two continuous variables. Does anyone know if a PGLS approach is valid with these trait types? Would this not effectively be trying to do a regression between two points because of the discrete binary independent variable? I'm unable to find any examples in the literature dealing with this scenario, but found an example here: http://tmfujis.wordpress.com/2013/08/22/phylogenetic-regression-part-1/ Thanks!

Re: [R-sig-phylo] ancestral estimation under OU model
thank you very much for your quick response!!! regards 2013/11/8 Liam J. Revell liam.rev...@umb.edu Hi Oscar. You can fit the OU model using (for example) fitContinuous in the geiger package, transform your tree using the fitted value of alpha, and then estimate ancestral states using BM. This will give you the same ancestral states as if you simultaneously fit the OU model to the tree. For instance: ## load packages library(phytools) library(geiger) ## fit OU model fit-fitContinuous(tree,x,model=OU) ## transform tree, could use transform.phylo ou-ouTree(tree,alpha=fit$opt$alpha) ## fit ancestral states, could use ace, anc.ML, etc. asr-fastAnc(ou,x) Let us know if this helps.
