The parameter estimation methods considered in this
thesis are the weighted Least-Squares and Weighted Huber
for some non-linear growth models. The properties of
these parameter estimators derived from simulated data
by means of (1) weighted and unweighted least-squares
and (2) weighted and unweighted Huber robust estimation
are compared. The error components of the simulated data
are long- tailed and non-normal. The performance of mis-specified
models is considered.
