boot_compare_cor {TOSTER}R Documentation

Comparing Correlations between independent studies with Bootstrapping

Description

A function to compare standardized mean differences (SMDs) between studies. This function is intended to be used to compare the compatibility of original studies with replication studies (lower p-values indicating lower compatibility)

Usage

boot_compare_cor(
  x1,
  y1,
  x2,
  y2,
  alternative = c("two.sided", "less", "greater", "equivalence", "minimal.effect"),
  method = c("pearson", "kendall", "spearman", "winsorized", "bendpercent"),
  alpha = 0.05,
  null = 0,
  R = 1999,
  ...
)

Arguments

x1, y1

numeric vectors of data values. x and y must have the same length from study 1.

x2, y2

numeric vectors of data values. x and y must have the same length from study 2.

alternative

a character string specifying the alternative hypothesis, must be one of "two.sided" (default), "greater", "less", "equivalence" (TOST), or "minimal.effect" (TOST). You can specify just the initial letter.

method

a character string indicating which correlation coefficient is to be used for the test. One of "winsorized", "bendpercent","pearson", "kendall", or "spearman", can be abbreviated.

alpha

alpha level (default = 0.05)

null

a number indicating the null hypothesis. Default is a correlation of zero.

R

number of bootstrap replicates

...

further arguments to be passed to or from methods.

Value

A list with class "htest" containing the following components:

"p.value"

numeric scalar containing the p-value for the test under the null hypothesis.

"estimate"

difference in correlations between studies.

"conf.int"

percentile (bootstrap) confidence interval for difference in correlations.

"null.value"

the specified hypothesized value for the null hypothesis.

"alternative"

character string indicating the alternative hypothesis (the value of the input argument alternative). Possible values are "greater", "less", or "two-sided".

"method"

a character string indicating how the association was measured.

"data.name"

Names of input values..

"boot_res"

List of bootstrapped results.

"call"

the matched call.
