1. Use orthogonal coding to code this design. Indicate which columns are for which effects. Hint: More columns are provided than are needed.
x1 x2 x3 x4 x5 x6 x7 x8 x9 x10 a b c d e f g h i j k l2. Give the Stata commands beginning with regress that will test the A main effect or use R2's to compute the F-ratio for A main effect.
Stata commands: or / ( ) F = ______________________________________ ( ) / ( )*****
