Abstract:
The power of the conventional Houck’s model of asymmetry is examined via parametric bootstrap
simulation. The results of the bootstrap simulations indicate that the Houck’s model has low power in
rejecting the null of symmetric adjustment. The power of the test depends on the bootstrap sample size, level
of asymmetry and the amount of noise in the data generating process used in an application. With a small
bootstrap sample and large noise level, the Houck’s model display low power in rejecting the null hypothesis
of symmetry.
