dataTOSTpaired: TOST Paired Samples T-Test

In TOSTER: Two One-Sided Tests (TOST) Equivalence Testing

TOST Paired Samples T-Test

Description

TOST Paired Samples T-Test in jamovi. This function is not meant to be utilized in R. See t_TOST function.

Usage

dataTOSTpaired(
  data,
  pair1,
  pair2,
  hypothesis = "EQU",
  low_eqbound = -0.5,
  high_eqbound = 0.5,
  eqbound_type = "raw",
  alpha = 0.05,
  desc = FALSE,
  plots = FALSE,
  low_eqbound_dz = -999999999,
  high_eqbound_dz = -999999999,
  indplot = FALSE,
  diffplot = FALSE,
  smd_type = "g"
)

Arguments

data	the data as a data frame
pair1	A string naming the first part of the pair
pair2	A string naming the second part of the pair
hypothesis	'EQU' for equivalence (default), or 'MET' for minimal effects test, the alternative hypothesis.
low_eqbound	a number (default: 0.5) the lower equivalence bounds
high_eqbound	a number (default: 0.5) the upper equivalence bounds
eqbound_type	'SMD' (default) or 'raw'; whether the bounds are specified in standardized mean difference (Cohen's dz) or raw units respectively
alpha	alpha level (default = 0.05)
desc	TRUE or FALSE (default), provide descriptive statistics
plots	TRUE or FALSE (default), provide plots
low_eqbound_dz	deprecated
high_eqbound_dz	deprecated
indplot	TRUE or FALSE (default), provide plot of paired data.
diffplot	TRUE or FALSE (default), provide plot of difference scores.
smd_type	'd' (default) or 'g'; whether the calculated effect size is biased (d) or bias-corrected (g).

Value

A results object containing:

results$text					a html
results$tost					a table
results$eqb					a table
results$effsize					a table
results$desc					a table
results$plots					an image
results$indplot					an image
results$diffplot					an image

Tables can be converted to data frames with asDF or as.data.frame. For example:

results$tost$asDF

as.data.frame(results$tost)
