Clive Granger dies

The Nobel prize winning econometrician has died. He introduced the
ideas of cointregration and causality. Great loss.

Labour and child poverty

It seems to have gone under in the turmoil around the expenses but the latest statistics show that Labour is way off its 2010 target of halving child poverty. The number of children in relative poverty before housing costs has stayed the same between 2006/7 and 2007/8 - at 2.9 million. This means only half a million lifted out of poverty since Labour came into power. Labour is not the party of equality.

Kanich et al of Berkeley and UCSD in ‘Spamalytics: An Empirical Analysis of Spam Marketing Conversion’ have run a trial to calculate the spam conversion rates for three bogus campaigns. I have recalculated the rates based on emails actually delivered.
