Title:
 A new approach to parameters estimation in polynomial regression with replications

Language: English

Keywords:
polynomial regression
repeated observations
growth curves
repeated measures

Summary:
The paper shows a unified method of estimating parameters of regression with replicated observations, taking into account assumptions of both equal and different variances. In a specific range of values of the independent variable, polynomial regression was considered because of its frequent use in the life sciences. For the considered multivariate approach we present an exemplary procedure (SAS 9.1), which allows one to make appropriate calculations.
