Hello! I have a dataset with monthly temperatures for 4 different years and I would like to test if they are significantly different between the years. As I collected the data for different sites I wondered if there were some possibility to perform the calculation at once or if I have to repeat it for each site.
I tried like this: Model_Temp <- lmer(Temp ~Year + (1|Site)+(1|Month),na.action=na.omit, data= MeanTemp) But I am not sure at all if it is correct to put the sites as random factors or if I have to do the calculation for each site separately. I am not interested in correlation between sites, but only between years for each different site. Alternatively, can you indicate me some way to plot this?
