Design Matrix example“Single Subject - conditions only” design

Y1 = 1b1 + 0b2 + 0b3 + (Dg1)bg or Y1 = b1 + (Dg1)bg
Y2 = 1b1 + 0b2 + 0b3 + (Dg2)bg or Y2 = b1 + (Dg2)bg
Y3 = 1b1 + 0b2 + 0b3 + (Dg3)bg or Y3 = b1 + (Dg3)bg
Y4 = 0b1 + 1b2 + 0b3 + (Dg4)bg or Y4 = b2 + (Dg4)bg
Y5 = 0b1 + 1b2 + 0b3 + (Dg5)bg or Y5 = b2 + (Dg5)bg
Y6 = 0b1 + 1b2 + 0b3 + (Dg6)bg or Y6 = b2 + (Dg6)bg
Y7 = 0b1 + 0b2 + 1b3 + (Dg7)bg or Y7 = b3 + (Dg7)bg
Y8 = 0b1 + 0b2 + 1b3 + (Dg8)bg or Y8 = b3 + (Dg8)bg
Y9 = 0b1 + 0b2 + 1b3 + (Dg9)bg or Y9 = b3 + (Dg9)bg
