The Wald confidence interval for the difference between probabilities

Source: R/Wald_CI_CC_2x2.R

The Wald confidence interval for the difference between probabilities with Yates's continuity correction. Described in Chapter 4 "The 2x2 Table"

Wald_CI_CC_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

# An RCT of high vs standard dose of epinephrine (Perondi et al., 2004)

#> The Wald CI with continuity correction: estimate = 0.1765 (95% CI -0.0002 to 0.3532)

# The association between CHRNA4 genotype and XFS (Ritland et al., 2007)

#> The Wald CI with continuity correction: estimate = -0.2083 (95% CI -0.3403 to -0.0763)
