derivs

<p>List of functions, each a derivative of a phi loss.</p>

A quadratic time dynamic programming algorithm
can be used to compute an approximate solution to the problem of
finding the most likely changepoints
with respect to the Poisson likelihood, subject
to a constraint on the number of segments, and the changes which must
alternate: up, down, up, down, etc. For more info read

for peak detection in count data" by TD Hocking et al,
