I bought a goat back in the spring. It delivered a kid, and I milked the nanny goat all summer. Now I've got several months of twice-daily milking data from this goat (weight in grams of milk). I don't know what statistical methods I can apply to this data, or, more specifically, which ones will tell me new and exciting things about the data beyond the basics (running averages, running variance, etc.). What are the usual methods used for this kind of biological data?
