GLM and MANOVA Syntax - Keyword Repeated
REPEATED [=] | { NONE } |
{ Name Value Name Value ... Name Value}; |
- Example
- REPEATED = TIME 3 DIALS 3;
Optional keyword; specify the names and number of levels for the repeated measures factors; specify the within-subject (repeated measures) design via the WDESIGN keyword; if no WDESIGN is specified, the analysis will be performed on the within-model intercept, i.e., effectively on the overall mean for the variables specified in the DEPENDENT variable list.
- Assignment of dependent variables to levels of the repeated measures factors
- Consecutive variables in the dependent variable list (specified via the
DEPENDENT keyword) are assigned to the levels of the repeated measures factors. Let p be the product of the levels of all repeated measures factors defined with the
REPEATED keyword. In the Example shown above, p would be equal to 3*3 = 9. Divide the number of dependent variables m by p to determine the number of dependent measures; if the modulo of (n, p) is not equal to 0 (i.e., m/p is not an integer value greater or equal to 1), an error message will be issued. To assign the consecutive dependent variables to the levels of the repeated measures factors, STATISTICA will cycle through a nested loop, where the number of dependent measures has the fastest moving subscript, the last specified repeated measures factor the next-to-fastest moving subscript, the next-to-last specified repeated measures factor has the next slower moving subscript, and so on.
For example, suppose the DEPENDENT variable list consisted of variables DV1, DV2, DV3, DV4, DV5, DV6, DV7, DV8, and the REPEATED measures of R1 with 2 levels, and R2 with 2 levels. The assignment of dependent variables to the levels of the repeated measures factors will then proceed as follows:
DV Level for Level for Dependent R1 R2 Measure DV1 1 1 1 DV2 1 1 2 DV3 1 2 1 DV4 1 2 2 DV5 2 1 1 DV6 2 1 2 DV7 2 2 1 DV8 2 2 2 Applies to. GLM and ANOVA/MANOVA
