Nested ANOVA with covariates
...each of these 4 reps, I have pseudoreplication. Specifically, I have 3 reps within each of the 4 main reps. In detail, worms are held in little wells in plates (random factor). I have 4 plates for each combination of cadmium and electic field. These are geniune reps. Within each plate, there are 3 pseudoreps. I thought I could model this as; aov(stress~cadmium + cadmium:plate + electic + electic:plate + cadmium:elecric+ cadmium:elecric:plate + Error(??????)) I don't really know what to put in the error. Thanks v much for your time. Regards, Martin. Martin Hoyle, School of Life and Environme...
