How do I compare 47 GLM models with 1 to 5 interactions and unique combinations?
...clude another variable in the model? How do I know when to stop? Definitions of Variables: HTL - distance to high tide line (continuous) Veg - distance to vegetation Aeventexhumed - Event of exhumation Sector - number measurements along the beach Rayos - major sections of beach (grouped sectors) TotalEggs - nest egg density Example of how all models were created: Model2.glm <- glm(cbind(Shells, TotalEggs-Shells) ~ Aeventexhumed, data=data.to.analyze, family=binomial) Model7.glm <- glm(cbind(Shells, TotalEggs-Shells) ~ HTL:Veg, family = binomial, data.to.analyze) Model21.glm <- glm(cbind(S...

Q - scatterplots
I was able to make a scatterplot but ... 1) what does the "86" mean? The "86" shows up on the graph as well. > scatterplot (Shells/TotalEggs ~ Sector, data = data.to.analyze) [1] "86" 2) Also how do you change the Y axis title? I don't want it to read Shells/TotalEggs, instead I would like it to read Average Hatching Rate (%). 3) What does this error mean? Rayos if composed of section 1, 2, 3, 4 and 5 > scatterplot (...

...-values in the binomial were more significant for each section of the beach. -- telling me more about the beach. Is this ok? Can I just look at the binomial glm model 25 and look at its p-values for beach sections and forget about the quasibinomial model 25?
