INTERPRETING COMPARATIVE EXPERIMENTS ON PARASITE BURDENS IN ANIMALS USING RANDOMIZATION AND CANONICAL VARIATES

Comparative experiments on parasite burdens present difficulties for m odelling and interpretation: data tend to have highly skewed distribut ions, some standard methods of testing for effects have low power, and there is a need to make allowance for dependencies among the various measurements, Randomization testing and canonical variates analysis ar e advocated as a means of minimising these problems.
