摘要
搜集整理188艘豪华邮轮的船型资料,分析豪华邮轮各主尺度要素的特点,运用统计学方法处理统计数据,分别用单变量回归、多元回归分析和BP神经网络回归方法建立豪华邮轮主尺度的数学模型,并对回归结果进行验证和误差分析,经检验,得到的回归公式误差较小。
Information of 188 luxury cruises was collected to analyze their characteristics and the relationship between dimension factors.The statistic method was used to deal with the data and mathematical models of the principal dimensions were established by single variable regression analysis,multiple regression analysis and BP neural network.The regression results were tested and investigated.It was verified that the error of the regression formula is small.
