A Trigonometric Curve Fitting on Animal Dataset

Abstract

In the traditional growth curve or milk yield models used in animal husbandry; models such as Brody, Von Bertalanffy, Logistic, Gompertz and Richards are used based on classical regression analysis. In this study, an alternative growth curve or milk yield model was proposed with the help of sinusoidal functions based on trigonometric functions. In this model, a sinusoidal curve model fitting and parameter estimation have been made by using a numerical sample of milk yield data set. In addition, this study aims to explain the applicability of periodic features of sinusoidal functions in agriculture and animal data. It is thought that this solution which can be applied in different fields will be beneficial for researchers.
