Figures & data
Figure 1. Heuristic examples for Tau and Tau-U analyses. Data series presented are hypothetical single-case AB designs with baseline phase followed by experimental phase.
Figure 2. Dependent variable scores are arranged in chronological order along the horizontal edge of a matrix from left to right, and in chronological order along the vertical edge of the matrix from bottom to top. Pairwise comparisons are made in a time-forward fashion within the corresponding cells of the matrix, with a “+” representing a concordant pair, a “−” representing a discordant pair, and a “T” representing a tied pair. For Figure 2A, S = 3, npairs = 45, and τ = .7. For Figure 2B, S = 5, npairs = 45, and τ = 5/45 = .1. (A) Difference matrix for time series in Figure . (B) Difference matrix for time series in Figure 1E.
