Safe Seats: Are MPs really at risk?
An MP stands a risk of losing his or her job at every general election. If their electorate is dissatisfied they can be sacked. But how many MPs are genuinely at risk of losing their seat? This analysis looks at the facts from history and estimates which current MPs are immune from public opinion. The analysis also involves some intereting extreme scenarios.
Posted 13-Sep-2009

Regional Swing Prediction
Using a large-sample YouGov poll we are able to measure regional swing and discover that previous "depolarisation" trends are continuing. Labour are relatively losing ground in the north, and gaining in the south. The overall effect is for the Conservatives to gain about 10 seats at the expense of Labour.

Strong Transition Model
Description of Electoral Calculus' advanced prediction model, which builds on the basic transition model, but with extra features to incorporate incumbency and local party strength. The model has been particularly designed to cope with weakened parties, such as the Lib Dems in autumn 2007.

Liberal Democrat wipeout?
Predictions in October 2007 show the Lib Dems with no seats, which is obviously a bit low. This analysis looks at why the model says this, the history of predicting Lib Dem results, and why the outlook for them looks bad under any model

Transition Model for Predictions
A full description of Electoral Calculus' basic transition model for predicting elections. The new model avoids some problems of the additive swing model, whilst retaining its good properties, and making very similar predictions for which party will actually win each seat. Backtesting each model against the 1987-2001 elections showed quite good performance from both, with the Transition Model being slightly, but not significantly, more accurate.
