If you have a demographic model of twitter users and appropriately re-weight, why is this a bad approach to take?
- eveningcoffee 10y agoIf I understood correctly then this was considered as a not necessary step. Now given the Twitters nature then is there such a model that is even approximately accurate? Or in other words, what relevant data Twitters collects and how accurate it is?
- Godel_unicode 10y agoBecause you don't (and probably can't) know that this model is accurate? Also, there are a lot of populations which are not present on Twitter at all, and more which are not present in meaningful numbers.
- dapz 10y agoSuch models presumably can be tested in some sense. E.g. build some sort of predictive model of elections in each state using Twitter users as a surrogate, see how well you do. I'm not claiming that such a model is guaranteed to be perfect or even as good as a pollster, but it sounds in principle like a reasonable thing to do, if you take appropriate precautions to reduce bias.
- eveningcoffee 10y agoAt least one can try definitely.
