সারসংক্ষেপ	Celeration line analysis is a single-case method that fits a trend line to the baseline phase, projects that line forward into the intervention phase, and judges effect by how many intervention data points fall on the improvement side of the projected trend. Built on Owen White's split-middle technique from precision teaching and codified for social-work practice by Bloom, Fischer, and Orme, it directly addresses a weakness of level-only comparisons: it asks whether the client improved beyond the trajectory the baseline was already on, and pairs the count with a simple binomial test for statistical decision-making.	Tau-U is a rank-based effect-size index for single-case research that combines the degree of nonoverlap between baseline and treatment phases with the trend within phases, and that can optionally subtract out any improving trend already present in the baseline. Developed by Richard Parker, Kimberly Vannest, and colleagues in 2011, it extends the Nonoverlap of All Pairs (NAP) statistic by adding a Kendall-style trend component, giving practitioners a single index that is robust to outliers, has a known sampling distribution for significance testing, and does not unfairly credit a treatment for change that the baseline was already heading toward.
