The Wald confidence interval for the ratio of paired probabilities

Described in Chapter 8 "The Paired 2x2 Table"

Wald_CI_ratio_paired_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.

Examples

# Airway hyper-responsiveness before and after stem cell transplantation
# (Bentur et al., 2009)
Wald_CI_ratio_paired_2x2(bentur_2009)
#> The Wald CI: estimate = 0.2500 (95% CI 0.0625 to 0.9996)

# Complete response before and after consolidation therapy
# (Cavo et al., 2012)
Wald_CI_ratio_paired_2x2(cavo_2012)
#> The Wald CI: estimate = 0.8667 (95% CI 0.7597 to 0.9886)
