Example please? Always thought of these as H0 = effect does not exist. H1 = effect exists. (apologies for missing something obvious).

Not necessarily. We can entertain any number of hypotheses at once. The last one can represent "anything else".

Thanks! In @thattai's tweet above, what's H2 supposed to represent? Isn't H1 a complement of H0 (so H0 U H1 is exhaustive set)?

Chris aldrich your blog is too good, i like your blog.
