Research On the Pricing Model of Second-Hand Sailboats Based on GDBT Model

Abstract

Sailboats have varying values with changes in market conditions and aging. This paper analyzed the characteristics and economic characteristics of monohull along with catamaran in their respective regions. The paper also carried out Spearman correlation analysis on their listing prices. The gradient boosting decision tree model was established to calculate the feature importance of each variable on the listing price, and the accuracy of the model reached over 86%. It indicated that the model can effectively price the second-hand sailboat market. This paper used one-way ANOVA to determine whether there was a significant difference between the listing prices of monohull and catamaran in the secondary markets. There were significant differences in the listing prices of monohulled sailboats and catamarans in different geographical regions. The listing prices of monohull and catamaran in different geographical regions were significantly different, and the regional effects were inconsistent.
