Wikipedia It is little comfort to the election predictors/modellers that Wikipedia has now decided to record for posterity how successful they were in predicting the party seat outcome of GE17. The chart is above. As can be seen only the YouGov model based on 50k+ of its own interviews came out of this well. Throughout the campaign the forecaster/modellers aimed to produce projections of the party seat totals which, are course, based on the outcome of 650 separate first past…

Tonight on #c4news: CPS confirm 15 separate police forces have sent files on 30 Tory MPs and agents relating to #electionexpenses scandal. — Hayley Barlow (@Hayley_Barlow) April 26, 2017 Keeping within the limits could make a difference Becasuse so much of the effort to predict and analyse the next election is based on what happened in each seat at GE2016 we are in something of a quandary because of what we know now about the Conservative approach to constituency expense…

Reminder the PB pre May 7th gathering tomorrow. The Shooting Star from 7pm

What happened at GE2010 when you exclude Scotland One of the reasons why the latest Electoral Calculus projection, see previous thread, appeared to be so good for LAB was the way Scotland and England/Wales were treated. This is the response I got from Martin Baxter on the computation:- “The overall prediction is based on both the national (GB) polls and the Scotland-specific polls. For Scottish seats, the prediction is just based on the Scottish Westminster VI polls, and for England…

Latest from Electoral Calculus http://t.co/yOyYu1w1VO has LAB 5 short of majority pic.twitter.com/3r8BdjnsmU — Mike Smithson (@MSmithsonPB) December 31, 2014 I can’t quite work out how Martin Baxter is handling his monthly predictions given the sharp rise of the SNP. From his latest data, out last night, he appears to have made his usual national computation and then over-ridden the Scottish seat data with his Scotland specific seat calculation.
