In this paper, we discuss the efficiency of noise reduction for curve fitting in nonlinear growth curve models We use singular spectrum analysis as a nonlinear-nonparametric denoising method A set of longitudinal measurements is used in considering the performance of the method we also use artificially generated data sets with and without noise for the purpose of validation of the results obtained in this study The results show that noise reduction is important for curve fitting in growt
