To estimate the ventilation volume of mechanically ventilated swine farms, various regression models were applied, and errors were compared to selectthe regression model that can best simulate actual data. Linear regression, linear spline, polynomial regression (degrees 2 and 3), logistic curve,generalized additive model (GAM), and gompertz curve were compared. Overfitting models were excluded even when the error rate was small. Theevaluation criteria were root mean square error (RMSE) and mean absolute percentage error (MAPE). The evaluation results indicated that degree 3exhibited the lowest error rate; however, an overestimation contradiction was observed in a certain section. The logistic curve was the most stable andsuperior to all the models. In the estimation of ventilation volume by all of the models, the estimated ventilation volume of the logistic curve was thesmallest except for the model with a large error rate and the overestimated model.
