What the heck is going on here?

This is a very simple simulation of the upcoming South Australia State election

  • The election is simulated 50K times adding in random polling errors

  • 100 simulated elections are shown on a line graph, sorted from highest incumbant seats to least incumbant seats
  • This model is limited and likely under predicting crossbench seats
  • Seemingly paradoxically I think that it's also overestimating the chance of a hung parliament
  • Tweaks are needed to preference flows - on a 2PP of ALP 50 - 50 Coalition it seems to unrealistically favour one side by a large margin
