ITSSIM: Interrupted Time-Series Simulation
- ITSSIM is a computer simulation method for analyzing single-case experimental data. ITSSIM models level, trend, variability, and autocorrelation parameters, and it yields effect size estimates appropriate for evidence-based clinical practice and meta-analysis.
- ITSSIM is accessible via free software download and requires no previous statistical computing experience.

Calculators
Baseline Corrected Tau
- Baseline Corrected Tau is a nonparametric effect size statistic for single-case experimental designs. Baseline Corrected Tau uses Theil-Sen robust regression and Kendall's rank correlation coefficient to control for statistically significant baseline trend and measure phase independence.

PND: p-values
- The percentage of nonoverlapping data (PND) is a widely used statistic for the measurement and meta-analysis of single-case experimental designs. This calculator yields exact p-values for PND.
