Single-case (SCED) effect-size summary

Source: R/sced.R
scedStats.Rd

Summarises the nonoverlap / trend effect sizes for a two-phase (A/B) single- case series, delegating to the peer-reviewed estimators in PhysioClinStats: the Percentage of Non-overlapping Data (as a percentage), the Nonoverlap of All Pairs, and the baseline-trend-corrected Tau-U in its bounded tau-b ("scan") form.

Usage

scedStats(data, phase, improvement = c("increase", "decrease"))

Arguments

data

Numeric vector of observations, in session order.

phase

Vector of phase labels the same length as data; the first two phases (in order of appearance) are taken as A (baseline) and B (intervention).

improvement

"increase" (default) if higher scores are better, or "decrease" if lower scores are the goal.

Value

A data.frame of class "sced_stats" with columns metric and estimate (PND in [0, 100], NAP in [0, 1], Tau-U in [-1, 1]).
