How to Evaluate Therapeutic Trend During a Single-Case Baseline
Define the desired direction, inspect baseline trend toward that outcome, preserve uncertainty, and explain how improvement before treatment affects inference.
Clinician guide
How to Make a Single-Case Baseline Predictability Decision
Review baseline level, trend, variability, coverage, measurement quality, and clinical gates without relying on a universal stability cutoff.
Clinician guide
How to Handle Missing Outcomes in a Single-Case Randomization Test
Handle missing single-case randomization outcomes by preserving positions and reasons, applying one rule across assignments, and reporting sensitivity and limits.
Clinician guide
How to Handle a Protocol Deviation After Single-Case Random Assignment
Handle a single-case randomization deviation by protecting welfare, preserving assigned and delivered schedules, classifying the event, and reviewing analyses.
Clinician guide
How to Handle Unequal Assignment Probabilities in a Single-Case Randomization
Handle unequal single-case assignment probabilities by preserving the weighted draw, summing probability mass for the tail, and avoiding unweighted schedule counts.
Clinician guide
How to Randomly Assign Cases to Fixed Multiple-Baseline Staggers
Randomly assign enrolled cases to fixed multiple-baseline start positions, preserving the permutation set, probabilities, draw, contextual limits, and analysis.
Clinician guide
How to Randomize a Changing-Criterion Schedule
Randomize a changing-criterion schedule with design-specific step values, timing, permissible sequences, the prospective draw, safety limits, and review.
Clinician guide
How to Randomize Phase-Change Points in a Reversal Design
Randomize reversal-design phase changes with permissible windows, minimum phases, withdrawal and safety gates, a prospective draw, and delivered-schedule evidence.
Clinician guide
How to Build a Restricted Randomization Set for Alternating Treatments
Build a restricted alternating-treatment randomization set with balance, run-length, block, transition, and washout rules fixed before the sequence draw.
Clinician guide
How to Randomize Condition Order in an Alternating-Treatments Design
Randomize alternating-treatment order with a prospective sequence set, balance and carryover rules, the actual draw, delivered order, and matching inference.
Clinician guide
How to Randomize Intervention Starts Across Multiple-Baseline Tiers
Randomize multiple-baseline starts with tier windows, valid stagger combinations, probabilities, the prospective draw, delivered starts, and power limits.
