Dear all, For my research I need to perform a Levene's test on my data.I have not large experience with this test and with R,so I have some problems to use the leveneTest function. I read some previous posts on this topic but I cannot understand what I have to do. I have a five-columns data frame organised in the following way: number of observation, number of subject, score, type of treatment (I have 4 of them), number of replication (3 replications).
My idea was: leveneTest(score~treatm*rep,data.ex,center=median) where: treatm is the treatments' column rep is the replications' column data.ex is the data frame. thank you giovanna -- View this message in context: http://r.789695.n4.nabble.com/hel-on-leveneTest-tp3309158p3309158.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.
