GLM Specifying Repeated Measures Designs - Specifying More than One Repeated Measures Factor
If a design contains more than one repeated measures factor, the order in which they are specified determines the assignment of dependent variables to levels of the repeated measures factors. Statistica cycles through the dependent variable list, assigning variables to subsequent levels of the repeated measures factor. Specifically, the fastest-moving (changing) levels are those of the repeated measures factor which was specified last, the next-fastest moving (changing) levels are those of the repeated measures factor which was specified next to last, and so on.
- Example
- If 12 dependent variables were selected, and you want to specify a 2 x 2 x 3 repeated measures design, then the assignment of variables to levels should be as follows:
First 1 1 1 1 1 1 2 2 2 2 2 2 Second 1 1 1 2 2 2 1 1 1 2 2 2 Third 1 2 3 1 2 3 1 2 3 1 2 3 Dep. Var. 1 2 3 4 5 6 7 8 9 10 11 12 Note: the numbers in the last row of the example table above represent the consecutive numbers of variables in the list of dependent variables specified by the user, and not the numbers of those variables in the data file (e.g., the number 1 above, may represent variable number 256 in the data file).See also: Multivariate repeated measures designs and General ANOVA/MANOVA and GLM Notes - Specifying within-subjects univariate and multivariate designs.
