preprocess_SCD: 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
)

Value

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

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.

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)
