Run the following R code (copy and paste) to create some data: out1 <- rep( c(0,0,1), 3 ) out2 <- rep( c(1,0,1), 3 ) counts <- c(18,17,15,20,10,20,25,13,12) This is a variation on the data in the first example on the “glm” help page in R. The counts variable is our response variable and will be modeled as a Poisson variable, the out1 predictor variable will measure the difference between outcomes 2 (baseline) and 3, and out2 will measure the difference...

The data are the mean weights of ten eggs from each...
