Analog of least significant difference error bars for proportions
...-book, p.464, Michael Crawley recommends that error
bars for bar plots of normally distributed continuous response
variables with categorical explanatory variables be given by
1/2 of the least significant difference, where the least significant
difference is defines as
qt(0.975,degrees_of_freedom)*standard_error_of_the_difference.
The idea is that the above quantity visually conveys whether or not
the means are different more realistically than do standard errors.
I have analyzed proportions with categorical variables using
the glm function with a binomial error model. I wish to plot a bar
graph with the height of the ba...
