【摘要】 目的探索山东省青州市小学生主要眼病患病率与学校之间的对应关系以及不同眼病间的聚集性;指导学校的防治工作。方法应用对应分析对青州市12所小学15种眼病发病资料进行分析。结果得到各地区和各眼病的公因子及其负荷系数,并根据第一、二因子负荷系数绘制因子负荷平面图,可以分析不同眼病间的聚集性及其高发与低发学校的分布。结论将变量与研究单位结合起来的对应分析是对因子分析的有益补充,它可以分析二维数据阵的行因素与列因素之关系,达到研究目的。更多还原

【Abstract】 Objective To Study the congruent relationship between schools and 15 ocular diseases in Qingzhou and Guiding school prevention and control work. Methods Using correspondence analysis to study the data of ocular disease morbidity of 12 schools. Results Turning up the common factors of the schools and types of ocular disease morbidity and its factor loading, then drawing a graph of factor loading by using the first and second factor loading.The species and school distribution of ocular disease can be clearly analyzed in the loading factor chart of correspondence analysis. Conclution Correspondence analysis which combines the variables and research units is a beneficial supplement to the factor analysis.It can analyse the relationship between row and column variables for 2-dimention data,accordingly achieving the purpose.更多还原
