Dear colleagues,
Is it true if one were to regard a nonorthogonal design as equivalent
to an unbalanced design. Below are the definitions I use in support
of this:
-An unbalanced design has unequal number of observations per cell.
-A nonorthogonal design refers to any experimental design in which
the numbers of observations are not equal in each and every cell.
The definition for nonorthogonal is from the following paper:
Appelbaum,M.L. and Cramer,E.M.(1974): Some problems in the
Nonorthogonal Analysis of variance, vol.81,no.6,page 335.
I get the confusion if any because some emphasize nonorthogonal only
and not mention unbalanced.
Some clarification please!
Yours sincerely,
June E. Simakani(Mr)
