Mathematical models of growth and compartmental models
have been developed over a long period of time. Many growth
models are introduced to model the growth of different characteristics
of biological populations [1–4]. With the progress of time the
main emphasis shifted from the development of a family of growth
curves (describing the trend or average behavior of the population)
to objective ways of fitting these models on real datasets coming
from a variety of disciplines such as population ecology [5], plant
biology [6], population dynamics [7], demography [8], bacterial
growth [9], and behavioral ecology [10]. Recently there have been
more emphasis on the problems involved in using asymptotic
results to make inference from finite samples and on finding more
realistic ways to model the stochastic behavior of the data as the
assumption needed for a commonly used estimation method of
nonlinear least squares (thereafter, NLS) are often untenable.
Broadly we may distinguish two classes of mathematical models,
namely, the deterministic (involving differential/partial differential
equations) and the stochastic (involving probability models).
