Perform equivalence testing on paired samples

Description

Perform equivalence testing on paired samples

Usage

## S3 method for class 'data.frame'
paired_equivalence_test(
  x,
  y,
  y_type = c("both", "criterion", "comparison"),
  alpha = 0.05,
  na.rm = TRUE,
  scale = c("relative", "absolute"),
  absolute_region_width = NULL,
  relative_region_width = NULL,
  ...
)

## Default S3 method:
paired_equivalence_test(
  x,
  y,
  y_type = c("both", "criterion", "comparison"),
  alpha = 0.05,
  na.rm = TRUE,
  scale = c("relative", "absolute"),
  absolute_region_width = NULL,
  relative_region_width = NULL,
  ...
)

paired_equivalence_test(
  x,
  y,
  y_type = c("both", "criterion", "comparison"),
  alpha = 0.05,
  na.rm = TRUE,
  scale = c("relative", "absolute"),
  absolute_region_width = NULL,
  relative_region_width = NULL,
  ...
)

Arguments

x	numeric vector representing the (possibly surrogate) sample
y	numeric vector representing the (possibly criterion) sample. Index paired with x
y_type	classification of y for the purpose of analysis. Can be "criterion", "comparison", or "both".
alpha	the alpha level for the test
na.rm	logical. Omit mean values for mean calculations?
scale	character specifying whether the test should occur on an absolute or relative scale. Must be one of "relative" (default) or "absolute".
absolute_region_width	the region width for use when scale = "absolute"
relative_region_width	the region width for use when scale = "relative"
...	further arguments passed to methods. Currently unused.

Value

a 'paired_equivalence' object summarizing the test input and results

Note

If a value is not specified for the region width that corresponds with scale, a default value will be assigned with a warning.

Examples

set.seed(1544)
x <- data.frame(
  var1 = rnorm(500, 15, 4),
  var2 = rnorm(500, 23, 7.3)
)
y <- rnorm(500, 17.4, 9)

test_result <- paired_equivalence_test(
  x, y, relative_region_width = 0.25
)

lapply(test_result, head)
