This study evaluated the feasibility of using different coding systems for categorical variables when using continuous and categorical variables together for the modeling of the lactation milk yield of Awassi sheep. In the study, when all variables were included in the model, and Dummy Coding and Effect Coding methods were used for age, the effects of lactation duration, average daily milk yield, type of birth, and age 5 group were found to be statistically significant in addition to the constan
