preprocess_SCD: Clean Single Case Design Data

In scdhlm: Estimating Hierarchical Linear Models for Single-Case Designs

Clean Single Case Design Data

Description

Clean single case design data for treatment reversal and multiple baseline designs.

Usage

preprocess_SCD(
  design,
  case,
  phase,
  session,
  outcome,
  cluster = NULL,
  series = NULL,
  center = 0,
  round_session = TRUE,
  treatment_name = NULL,
  data = NULL
)

Arguments

design	Character string to specify whether data comes from a treatment reversal ("TR"), multiple baseline across participants ("MBP"), replicated multiple baseline across behaviors ("RMBB"), or clustered multiple baseline across participants ("CMB").
case	vector of case indicators or name of a character or factor vector within data indicating unique cases.
phase	vector of treatment indicators or name of a character or factor vector within data indicating unique treatment phases.
session	vector of measurement occasions or name of numeric vector within data of measurement times.
outcome	vector of outcome data or name of numeric vector of outcome data within data.
cluster	(Optional) vector of cluster indicators or name of a character or factor vector within data indicating clusters.
series	(Optional) vector of series indicators or name of a character or factor vector within data indicating series.
center	Numeric value for the centering value for session. Default is 0.
round_session	Logical indicating whether to round session to the nearest integer. Defaults to TRUE.
treatment_name	(Optional) character string corresponding to the name of the treatment phase.
data	(Optional) dataset to use for analysis. Must be a data.frame.

Value

A cleaned SCD dataset that can be used for model fitting and effect size calculation.

Note

If treatment_name is left null it will choose the second level of the phase variable to be the treatment phase.

Examples

data(Laski)
preprocess_SCD(design = "MBP", 
               case = case, phase = treatment,
               session = time, outcome = outcome, 
               center = 4, data = Laski)
               
data(Anglesea) 
preprocess_SCD(design="TR",
               case=case, phase=condition,
               session=session, outcome=outcome,
               treatment_name = "treatment",
               data=Anglesea)
               
data(Thiemann2001)
preprocess_SCD(design = "RMBB", 
               case = case, series = series, phase = treatment, 
               session = time, outcome = outcome, 
               data = Thiemann2001)
