The June 2010 recovery is pretty easy to see in the raw data.
At the very least (after adjusting for collective house effects) it would appear that Keven Rudd was removed from office on that fateful morning in June 2010 on a poll winning 52 per cent of the two-party preferred vote. We know what happened next.
Kevin in the comments below makes a valid point. The last few data points above slide into Julia's elevation bounce. I have changed the cut-off date from 24 June to 20 June and re-run the analyses. The key charts with this change follow.
I should point out that the observation count in the LOESS charts is the number of LOESS data points in the analysis. Where there are two polls on a date, only one point in the LOESS series is calculated.
