The Koopman asymptotic score confidence interval for the ratio of probabilities

Described in Chapter 4 "The 2x2 Table"

Koopman_asymptotic_score_CI_2x2(n, alpha = 0.05)

Arguments

n: the observed counts (a 2x2 matrix)
alpha: the nominal level, e.g. 0.05 for 95% CIs

Value

An object of the contingencytables_result class, basically a subclass of base::list(). Use the utils::str() function to see the specific elements returned.

Note

This versions uses the score test statistic of the Miettinen-Nurminen interval without the variance correction term.

Examples

#> Koopman asymptotic score CI: estimate = 7.0000 (95% CI 1.2209 to 42.5757)
Koopman_asymptotic_score_CI_2x2(ritland_2007)
#> Koopman asymptotic score CI: estimate = 0.0000 (95% CI 0.0000 to 0.9619)
