Permutation test for randomized complete block design
- 1 plant
- 5 plants
- 10 plants
Response is number of eggs in each treatment across 32 blocks
Can we do a permutation test to determine whether there is an effect of treatment?
For a blocked design, the permutation test should permute treatments within a block.
Previously used a negative binomial regression model.
How is the experiment run? Are all 32 blocks run simultaneously? Is there only one cage and it is reused 32 times. How many butterflies are put in each cage?
Permute treatments within a block
There is a decision to be made about whether the response is the number of eggs (in a treatment unit) or the number of eggs per plant (in a treatment unit).
