Dear SamiC, I am also attempting to plot my zero inflated model on my data. Did you find a solution? Does anyone else on this list have a solution?
Thanks, Liesl Message from SamiC Jun 30, 2011: I am fitting a zero inflated negative binomial model to my data. I have pretty much got my selected model and now i am wanting to plot the model to the origional data. Example. f8<-formula(Birds~Tide+Fish+Zooplankton+Chlorophylla|StratificationIndex) Nb8<-zeroinfl(f8, dist="negbin", link= "logit", data=ocean) Tide is a factor, so i assume i have to plot a different graph for each level of the factor. what i essentially want to do is plot a graph for each variables against birds with the fitted line of the model. I have been using the predict function, but i get the same trend for every graph and variable. I was reading that the predict function gives a mean across all the values (or something to this effect). Does anyone know how to code for this in R. from the above model i want to plot birds~fish (the original data) and then fit the line of the relationship from the model. -- View this message in context: http://r.789695.n4.nabble.com/Zero-Inflated-Models-Plotting-Results-tp3636373p4644800.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.
