Biased output?

Andrew,

I am using a setup very similar to your "TimeSeries" example.

Sometimes, after training I see a solution that is very biased - all results are to one side (usually positive) of zero. Yet I have scaled all my inputs, and my single output to -1,1 range.

If you can see the picture, the red dots represent the target output and the blue line is the solution.

What might cause such an obvious "bias"?
