yes I believe that some parties will be overrepresented if you solely look at the volume of tweets. This is simply due to the fact that Twitter in Turkey is more popular under young and educated people(1). It should however not be difficult to take this into account in the linear regression algorithm, because the tuning parameters can be determined with data from the previous elections.<p>I had made an prediction for each province after initially collecting all the tweets, but the results were not accurate. At the moment I have also determined the location of about 33% of the twitter accounts and I hope the result will be better if I exclude all Twitterers which are not from the same province as the one I am doing the calculation on.<p>Thanks for the feedback :)<p>(1) <a href="http:&#x2F;&#x2F;webrazzi.com&#x2F;2014&#x2F;07&#x2F;17&#x2F;genart-ve-nielsenin-turkiyede-twitter-kullanici-istatistikleri&#x2F;" rel="nofollow">http:&#x2F;&#x2F;webrazzi.com&#x2F;2014&#x2F;07&#x2F;17&#x2F;genart-ve-nielsenin-turkiyede...</a>
