Correlation Analysis of Second-Hand Sailboat Prices: Insights from Economic Indicators and Feature Significance

The table below displays the parameter results of model validation: it can be observed that price exhibits a strong correlation with 'Length' at the 1% level and a weak correlation with 'Draft' at the 5% level, while the remaining features demonstrate a significant moderate correlation.

Furthermore, employing the same principle, an analysis was conducted on the second-hand sailboat prices with economic data and year divided by region, including GDP, GNI, unemployment rate, and price level. The results indicate that unemployment rate has no impact on price, and thus, we have removed this indicator in the subsequent modeling process.
