Summary

[edit]

Wallis, Sean. Original image by author. A version of this plot is published in Wallis (2021: 180).[1]

Gaussian (normal approximation) intervals for n = 10 and n = 100 computed alongside an example logistic curve. Note examples of overshoot (the interval falsely predicts the true proportion p is outside its possible range [0, 1] and zero-width intervals (the interval falsely predicts the true proportion is exactly 0 or 1).
