简单交互效应和简单简单效应分析

简单交互效应和简单简单效应分析 between-subject design if three-way interaction is signifcant , compute the simple interaction effect. **********simple interaction effect******************** manova total by gender (1,2) depart (1,2) grade(1,3) /design = gender*grade within depart(1) gender*grade within depart(2). if the simple interaction effect is not signifcant , compute the simple effect.如果简单交互效应不显著， 那么就计算 ***************simple effect*********************** manova total by gender (1,2) depart (1,2) grade(1,3) /design = grade within depart(1) gender within depart(1). **************multiple comparisons***************** manova total by gender (1,2) depart (1,2) grade(1,3) /contrast (grade) = special (1 1 1 1 -1 0 1 0 -1) /design = grade within depart(1). manova total by gender (1,2) depart (1,2) grade(1,3) /contrast (grade) = special (1 1 1 1 -1 0 0 1 -1) /design = grade within depart(1). if the simple interaction is significant ,compute the simple simple effect.简单交互效应显著，计算简单简单效应。 ***********simple simple effect********************** manova total by gender (1,2) depart (1,2) grade(1,3) /design = grade within gender(1) within depart(2) grade within gender(2) within depart(2). ******************multiple comparisons******************* manova total by gender (1,2) depart (1,2) grade(1,3) /contrast (grade) = special (1 1 1 1 -1 0 1 0 -1) /design = grade within gender(2) within depart(2). manova total by gender (1,2) depart (1,2) grade(1,3) /contrast (grade) = special (1 1 1 1 -1 0 0 1 -1) /design = grade within gender(2) within depart(2). The within-subject design (组内设计)is similar to the between-subject design . You can change the “design” into “wsdesign(组内)”. And the command contrast is not adap to multiple comparisons in within –subject design. mixed-design if three-way interation effect is significant ,compute the simple interation effect.(如果三项交互效应显著，计算简单交互效应) *************simple interaction effect************* manova a1b1 a1b2 a1b3 a2b1 a2b2 a2b3 by freq(1,3) /wsfactors = a (2) b (3) /wsdesign = a*b /design = mwithin(混合设计) freq(1) mwithin freq(2) mwithin freq(3). if simple interaction effect is significant , compute the simple simple effect. ************simple simple effect ****************** manova a1b1 a1b2 a1b3 a2b1 a2b2 a2b3 by freq(1,3) /wsfactors = a (2) b (3) /wsdesign = a within b(1) a within b(2) a within b(3) /design = mwithin freq(1). manova a1b1 a1b2 a1b3 a2b1 a2b2 a2b3 by freq(1,3) /wsfactors = a (2) b (3) /wsdesign = b within a(1) b within a(2) /design = mwithin freq(1). if simple interaction effect is not significant , compute the simple effect. manova a1b1 a1b2 a1b3 a2b1 a2b2 a2b3 by freq(1,3) /wsfactors = a (2) b (3) /wsdesign = a b /design = mwithin freq(2). if simple interaction effect is significant , compute the simple simple effect. manova a1b1 a1b2 a1b3 a2b1 a2b2 a2b3 by freq(1,3) /wsfactors = a (2) b (3) /wsdesign = a within b(1) a within b(2) a within b(3) /design = mwithin freq(3). manova a1b1 a1b2 a1b3 a2b1 a2b2 a2b3 by freq(1,3) /wsfactors = a (2) b (3) /wsdesign = b within a(1) b within a(2) /design = mwithin freq(3).
