In mcradds: Processing and Analyzing of Diagnostics Trials

Compute Difference for Bland-Altman

Description

Helper function computes the difference with specific type.

Usage

h_difference(x, y, type)

Arguments

x	(numeric) reference method.
y	(numeric) test method.
type	(integer) integer specifying a specific difference for Bland-Altman (default is 3). Possible choices are: 1 - difference with X vs. Y-X (absolute differences). 2 - difference with X vs. (Y-X)/X (relative differences). 3 - difference with 0.5*(X+Y) vs. Y-X (absolute differences). 4 - difference with 0.5*(X+Y) vs. (Y-X)/X (relative differences). 5 - difference with 0.5*(X+Y) vs. (Y-X)/(0.5*(X+Y)) (relative differences).

Value

a matrix contains the x and y measurement data and corresponding difference.

Examples

h_difference(x = c(1.1, 1.2, 1.5), y = c(1.2, 1.3, 1.4), type = 5)
