Hi, FSL experts

    I designed a matrix to do 2-way ANOVA, here is the situation. In my design, there are 2 factors

factor1(4 levels):disease     L1    L2    L3    L4

factor2(2 levels):gender      G1    G2

also I want to control age.

my design matrix is :

EV1   EV2   EV3     EV4      EV5     EV6     EV7     EV8        EV9

1         1         1         1          1          1         1          1            3

1         1         1        -1          -1        -1        -1         1            -5

-1        0         0        -1          1         0         0           1           2

-1        0         0         1          -1        0         0           1           -1

0        -1         0         1          0          -1       0           1           -1

0        -1         0        -1          0         1         0           1           4

0         0         -1       -1          0          0        1           1          -3

0         0         -1        1          0          0        -1          1           1

 

EV1:L1>L2

EV2:L1>L3

EV3:L1>L4

EV4:G1>G2

EV5,6,7:interaction effect

EV8:mean

EV9:age(demeaned)

 

Is my design correct? 

 

Thank you.
