Confidence interval for the difference of two proportions: R code for

  • The Miettinen-Nurminen Interval (performs “better” than the score): MN

The score interval: score_int

  • This code is actually more general and let’s you compute the score interval for any linear combination of proportions! (See Andres et al. (2011) Stat. Meth. Med. Research.)

Note: These intervals are not what you would get from prop.test() in R. prop.test() returns the inferior clipped Wald interval with or without continuity correction. It should not be used. prop.test() can also not do the score test when the null difference of proportion is not 0.
