Re: [R] pseudoreplication
This should be posted on r-sig-mixed-models, not here. But you should realize that "equivalent analysis" presumes knowledge of what ASReml does, so that perhaps the best target of your query is the package maintainer, not a list concerned with other methods.

[R] pseudoreplication
Greetings R Community The ASReml-R package will analyze data from experiments with pseudoreplications. Dealing with Pseudo-Replication in Linear Mixed Models https://www.vsni.co.uk/case-studies/dealing-with-pseudo-replication-in-linear-mixed-models Will the ‘lme4’ package return an equivalent analysis of data from experiments with pseudoreplications?

[R] pseudoreplication - LME
Need some help please I am trying to use this model because I have temporal replication in my data results-read.table(file=file.choose(),header=T) attach(results) names(results) results-na.omit(results) library(nlme) library(lattice) results-groupedData(weight~date|group,outer=~diet,results) plot(results) plot(results,outer=T) model-lme(weight~diet,random=~date|group,results) everything worked till here although when I compute the model this error appears Error in lme.formula(weight ~ diet, random = ~date | group, results) : nlminb problem, convergence error code = 1 message = iteration limit reached without convergence (9) summary(model) http://n4.nabble.com/file/n948321/rawoctobercalciumexperiment2.xlsx rawoctobercalciumexperiment2.xlsx kind regards thank you in advance Ana -- View this message in context: http://n4.nabble.com/pseudoreplication-LME-tp948321p948321.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
