In the chapter, we used a subset of the data collected by Menezes and Elbert(1979) to study store image as sample problem. The full study actually examined four different dimensions of store image (appearance, product assortment, prices, and service) each measured using three methods (Likert, semantic differential, and Stapel). The complete 12*12 correlation matrix (base on n=250 observations) is available a)Diagram and test a four-factor model of store image (ignoring the different measurement methods for now). Describe your findings. Does the model provide an acceptable fit to the data? b)Modify the model in part a to account for the possible method correlation. How many additional degrees of freedom does the model require? Is the improvement in fit significant relative to the model in part a. 题目资料是一份correlation 排列方式是d(dimension)m(method) m1d1 m1d2 m1d3 m1d4 m2d1 m2d2 m2d3 m2d4 m3d1 m3d2 m3d3 m3d4 第一题叫我们忽略三个方法，想不出来怎麽忽略 是只需要用其中一种method就好了吗? 另外请问一下，除了Lisrel可以做验证性因素分析外，还有什麽软体能用吗? 我看的书上只有Lisrel 谢谢 -- 只要用力呼吸， 就会发现奇蹟。 只要没有呼吸， 就要发现上帝。 --
