目的—了解山东省某县2000-2002年恶性肿瘤的地区分布和肿瘤类型分布特征.方法—应用分组对应分析对该县恶性肿瘤死亡资料进行分析.结果—得到各地区和各肿瘤类型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,可以清楚看出恶性肿瘤死亡率的聚集性及其高发地与低发地的分布.结论—将变量与样本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.
OBJECTIVE- To understand the regional distribution and distribution of malignant tumors in a county in Shandong Province from 2000 to 2002.Methods - To analyze the death data of malignant tumors in this county by means of group correspondence analysis.Results - Common factors of each tumor type And its load factor, and according to the first and second factor load factor to draw the load map of factor load, we can clearly see the aggregation of malignant tumor mortality and the distribution of high incidence and low incidence.Conclusion - Combining variables with samples Correspondence analysis is a useful complement to factor analysis. It can analyze the relationship between row factors and column factors of two-dimensional data array, and achieve the purpose of research.
