Kenneth 及各位朋友:
* q% m2 ?4 A" M9 d/ s 我最近看到一项研究(modelingconsumer response to different levels of comparative advertising),在这项研究的模型图中,Cai(比较广告强度)有3个treatment [分别为direct comparative advertising (Cai =2), indirect comparative (Cai = 1) and noncomparative advertising (Cai = 0).] Rms(相对市场份额)有2个treatment [分别为low relative market share (Rms = 0) andmoderate relative market share (Rms = 1)]。然后作者根据Cai的3个水平×Rms的2个水平的6种情况,通过问卷共收集了6个样本(每种情况120个被调查者,共720位被调查者),然后用SEM对模型进行检验。
