Thank you Mitchell, I will try that. So I presume that the initial paper where they showed the estimates AND the intercept from a model averaging procedure may have been done using a different method? Would it still be prudent to use a global model and then perhaps show the top so many, perhaps

Hello, I have been attempting to set up a lme and have looked at numerous posts including 'R's lmer cheat-sheet' as well as reading a number of papers and other resources including R help, but I am still a little confused on how to write my model (I thought I had it). I have asked a number of

Hello Mike, I don't think I did, but I fixed the issue by loading each package before use. The second issue was solved by removing a variable that was used to create two other categorical variables. I think it must have been recognising this. Thanks for the help. -- View this message in

I realised that I removed the link to the question but forgot to remove the text regarding it. Sorry. I am not sure if I am supposed to link to other forums, but I can add the links as needed (as the format is clearer). I actually have one more question though in regards to which data to use. If

Hello all, If someone could take a little time to help me then I would be very grateful. I studied piping plovers last summer. I watched each chick within a brood for 5 minutes and recorded behaviour, habitat use and foraging rate. There were two Sites, the first with 4 broods and the second with

I understand where you are coming from, but the issue is that some exploration of the data through graphs and the like, showed that patterns could be seen. However with only 7 means it is extremely difficult to get any kind of statistical evidence and as some mean values are the same some of the

This was solved by loading each package right before using it (I thought you loaded both at the beginning). However I now have an additional issue. I ran a small model with just three factors to try it out and it worked beautifully, but when I tried to run it with all the factors this is what I

Hello, I hope that you can bare with me. I am new to models, but I think I have a pretty godd understanding of how to run them now, including how to use AICc and Anova. The issue is that I have many factors that I wish to compare so doing each one at a time would take forever. I came across the
