Classification and Regression Tree (CRT) Analysis to Predict Body Weight of Potchefstroom Koekoek Laying Hens

P otchefstroom Koekoek chicken genotype was devel- oped from crossbreeding three chicken genotypes namely White Leghorn, Black Australorp and Bared Plymouth Rock (Tyasi et al., 2019; Mutibvu et al., 2019).This chicken genotype has gender-specific feather colour and patterns, which make it easy for sexing of day-old chicks (Heit, 2017).According to Dessie and Gatachew (2016), this chicken genotype is well acclimatized to the tropical regions which enable it to thrive in many of hot environment of the African countries, and is suitable for free-range production system and can also thrive and perform highly in small-scale rearing system.Classification and regression tree (CRT) is a data mining algorithm commonly used where the dependent variable is categorical which help to identify the class within which a dependent variable fall into, and also used where the dependent variable is continuous which help to predict the Research
