39- Problem :
40- Given estimates of the abundance of the population of a marine
41- spieces at each stage as a function of time, determine specific
42- growth and mortality rates. Th emodel for the population dynamics
43- of the n_e -stage population is
44- y_j' = g_j-1 y_j-1 - (m_j + g_j) y_j (1 <= j <= n_e)

47- dies or grows into the next stage, with the implicit assumption that
48- the species cannot skip a stage. Initial conditions for the differntial
49- equation are unknown, since the stage abundance measurements at the
50- initial time might also be contaminated with experimental error. The
