§8.1多元回归分析 多元回归分析（MultipleRegressionAnalysis）研究一个依变量对两个或多个自变量(且自变量均为一次项）依存关系的统计分析方法。解决的问题：①确定各个自变量对于某一依变量的综合效应②在大量自变量中，选择仅对依变量有显著效应的自变量，建立最优的多元回归方程③评定各个自变量对于依变量的相对重要性...
Perform a Multiple Regression Analysis paralleling the HBAT analysis performed in the textbook and in class, but now use the HATCO dataset (see HATCO_X1-X14_Tabs data file). Include the following analyses: Consider the overall general Model X9 = X1 X2 X3 X4 X5 X6 X7 Perform a Correlation...

With regression analysis, we want to predict a number, called the response or Y variable. With linear regression, one independent variable is used to explain and/or predict the outcome of Y. Multiple regression uses two or more independent variables to predict the outcome. With logistic ...
