between_smd: Between-Case Standardized Mean Difference

In jazznbass/scan: Single-Case Data Analyses for Single and Multiple Baseline Designs

Between-Case Standardized Mean Difference

Description

Calculates a standardized mean difference from a multilevel model as described in Pustejovsky et al. (2014)

Usage

between_smd(data, ...)

## S3 method for class 'sc_bcsmd'
print(x, digits = 2, ...)

Arguments

data	Either an scdf or an object returned from the hplm() function.
...	When data is an scdf, further design parameters passed to the hplm() function.
x	An object returned by baseline_smd().
digits	The minimum number of significant digits to be use. If set to "auto" (default), values are predefined.

Functions

• print(sc_bcsmd): Print results

Examples

des <- design(
  n = 150,
  phase_design = list(A = 10, B = 10, A2 = 10, B2 = 10, c = 10),
  level = list(B = 1, A2 = 0, B2 = 1, c = 1)
)
study <- random_scdf(des)
between_smd(study)

model <- hplm(study, slope = FALSE, contrast_level = "preceding")
between_smd(model)
