I'm especially concerned since HW 7 uses all the same data again - so I really need to track this down.
Are you using lambda from 0.001 to 1000? I suppose it might be possible to forget to calculate the power. If you do this, the added term in the matrix described in this thread can hardly fail to have a significant effect.
