分析数据
为了了解某地母亲身高x与女儿身高Y的相关关系，随机测得10对母女的身高（见下表）。利用SPSS软件，完成以下任务：
1.画出x、Y散点图，观察因变量与自变量之间关系是否有线性特点；
2.试对x与Y进行一元线性回归分析，列出一元线性回归预测模型；
3.预测当母亲身高为161cm时女儿的身高？
母亲身高(cm) 159 160 160 163 159 154 159 158 159 157
女儿身高(cm) 158 159 160 161 161 155 162 157 162 156
Analyze the data in order to understand the correlation between height somewhere mother and daughter x height Y randomly measured 10 pairs of mother and daughter' s height (see table below). Use SPSS software, complete the following tasks: 1 Draw x, Y scatter, observe the relationship between the dependent variable and the independent variables are linear features 2 trial of x and Y be a linear regression analysis, a linear list. regression prediction model 3 predict when her mother height is 161cm tall when? Mother Height (cm) 159 160 160 163 159 154 159 158 159 157 daughter Height (cm) 158 159 160 161 161 155 162 157 162 156 (2014-05-12, Windows_Unix, 1722KB, 下载5次)
最小重量机器设计问题：设某一机器由N个部件组成，每一个部件都可以从M个不同的供应商处购得。设wij是从供应商j处购得部件i的重量，cij是相应的价格。试设计一个算法，给出总价格不超过C的最小重量机器设计。

我在程序文件中所使用的计算最小费用最大流的算法并没有先用福德－富克逊法算出最大流，然后再用对偶法算出最小费用，而是将两种算法结合，最小费用和最大流一起算出
I said in my program files used in the calculation of the minimum cost maximum flow algorithm does not first Ford- Fu Dixon calculated maximum flow and then calculated the dual minimum cost, but will combine two algorithms, minimum cost and calculate maximum flow together (2007-11-26, Windows_Unix, 1KB, 下载3次)
