Comment (by tscrim):
Hey Anne,
The reason why tests didn't break is because it is equivalent. To see
this, note that
{{{
a_i(k+1) = a_i(k) + \epsilon_i(b_{k+1}) - \phi_i(b_k)
}}}
which is how `_sig()` is recursively computed. However this way is much
more clear and clean. I've uploaded the folded patch and pushed to the
queue.
Best,[[BR]]
Travis
