D. In an additive model for a twofactor experiment, SST=SSA+SSB+SSE. ANSWER: A
When
, a valid estimator of
can be obtained without assuming additivity.
(cf. p.433 for A, p. 422 for B, p. 433 for C, p. 424 for D) 10. The transformation
of the dependent variable y and the transformation
of
the independent variable x are used to linearize the function
. Then, then transformed linear
equation will be
