R Documentation

The Wald test and confidence interval for the difference between marginal mean scores

Description

The Wald test and confidence interval for the difference between marginal mean scores

Described in Chapter 9 "The Paired cxc Table"

Usage

Wald_test_and_CI_marginal_mean_scores_paired_cxc(
  n,
  a = seq_len(nrow(n)),
  alpha = 0.05
)

Arguments

n	the observed table (a cxc matrix)
a	scores assigned to the outcome categories
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

# A comparison between serial and retrospective measurements
# (Fischer et al., 1999)
a <- c(8, 3.5, 0, -3.5, -8)
Wald_test_and_CI_marginal_mean_scores_paired_cxc(fischer_1999, a)
