简单效应分析 Simple main effect 必要性 方法： 改写EMMEANS语句 编写MANOVA语句 改写EMMEANS语句 Paste到syntax UNIANOVA grade BY textbook method /METHOD = SSTYPE(3) /INTERCEPT = INCLUDE /POSTHOC = textbook method ( LSD T2 ) /EMMEANS = TABLES(textbook) COMPARE ADJ(LSD) /PRINT = DESCRIPTIVE HOMOGENEITY /CRITERIA = ALPHA(.05) /DESIGN = textbook method textbook*method . 改写EMMEANS语句 检验textbook在method上的简单效应 UNIANOVA grade BY textbook method /METHOD = SSTYPE(3) /INTERCEPT = INCLUDE /EMMEANS = TABLES(textbook*method) COMPARE（ textbook ） ADJ(LSD) /CRITERIA = ALPHA(.05) /DESIGN = textbook method textbook*method . 检验method在textbook上的简单效应 UNIANOVA grade BY textbook method /METHOD = SSTYPE(3) /INTERCEPT = INCLUDE /EMMEANS = TABLES(textbook*method ) COMPARE (method) ADJ(LSD) /CRITERIA = ALPHA(.05) /DESIGN = textbook method textbook*method . 编写MANOVA语句 检验textbook在method上的简单效应 MANOVA grade BY textbook(1,2) method(1,3) /DESIGN = textbook within method(1) textbook within method(2) textbook within method(3) . 检验method在textbook上的简单效应 MANOVA grade BY textbook(1,2) method(1,3) /DESIGN = method within textbook (1) method within textbook (2). 二因素分析，包括简单效应，多重比较检验！ GLMa1b1 a1b2 a2b1 a2b2 /WSFACTOR = A 2 Polynomial B 2 Polynomial/METHOD = SSTYPE(3)/EMMEANS = TABLES(A*B) COMPARE (A) ADJ(LSD)? /在B因素的各个水平上A因素的各个水平的多重比较(LSD方法) /EMMEANS = TABLES(A*B) COMPARE (B) ADJ(LSD)? /在A因素的各个水平上B因素的各个水平的多重比较(LSD方法)/PRINT = DESCRIPTIVE/CRITERIA = ALPHA(.05)/WSDESIGN = A B A*B. ? 三因素条件 ? GLMa1b1c1 a1b1c2 a1b2c1 a1b2c2 a2b1c1 a2b1c2 a2b2c1 a2b2c2 /WSFACTOR = A 2 Polynomial B 2 Polynomial C 3 Polynomial/METHOD = SSTYPE(3)/EMMEANS = TABLES(A*B) COMPARE (A) ADJ(LSD)????? /* A 因素在B因素各个水平上的效应（多重比较采用LSD）/PLOT = PROFILE ( A*B)?????? ? /* 作图(A as 横轴, B为横轴)/EMMEANS = TABLES(A*B*C COMPARE (A) ADJ(LSD)???? /* A因素在B*C结合的各水平上的效应./PRINT = DESCRIPTIVE/CRITERIA = ALPHA(.05)/WSDESIGN = A B C A*B A*C B*C A*B*C. ? 以上全部是重复测量方差分析的例子，其
