Design Matrix example “Single Subject - conditions
only” design
- three-way Ancova design for a single subject activation
experiment with 3 scans in each of 3 conditions
(categorical design).
- 1 subject, 3 conditions, 3 scans per condition
- MODEL: Yi = g1ib1 + g2ib2 + g3ib3 + (Dgi)bg
Each row corresponds to an individual scan. Each column
corresponds to a covariate: condition indicator variables
(0=gray, 1=white) for conditions 1-3 in columns 1-3 and gCBF
correction covariates in column 4. Scans 1-3 are condition 1, 4-6
are condition 2, and 7-9 are condition 3.
