Count Method Failures as Simulation Results

Track nonconvergence and invalid outputs without letting successful subsets make a method look artificially reliable.

Build a Simulation Scenario Grid Before Running Methods

Separate scientific conditions, performance measures, and computational replication in a traceable design.

Document Spline Knots and Reuse the Fitted Basis

Preserve spline construction so predictions use the same transformation as the fitted model.

Audit Stabilized Inverse-Probability Weights From Numerator to Outcome Model

Check probability definitions, weight distributions and the assumptions retained after stabilization.

Separate calendar time from stepped-wedge exposure

Audit crossover timing, calendar periods and correlation before analysing a stepped-wedge trial.

Prepare a Precise Request for Missing Study Information

Specify the missing quantity, its intended use, and a traceable response record before contacting study investigators.

Check Design Degrees of Freedom Before Using a Large-Sample Interval

Relate survey uncertainty to independent sampling information rather than the number of records alone.

Estimate a Survey Subpopulation Without Losing Its Design

Define the target domain while retaining the sampling information needed for uncertainty.

Distinguish Empty Survey Cells From Observed Zero Outcomes

Keep absent information visible when reporting subgroup estimates and tables.

Audit Survey Strata and Primary Sampling Unit Identifiers

Check nesting, singleton strata and design metadata before estimating survey uncertainty.

Review Weight Trimming as a Bias–Precision Tradeoff

Investigate influential survey weights and document a justified trimming sensitivity analysis.

Align Eligibility, Treatment Assignment and Follow-Up at Time Zero

Write the hypothetical trial before translating an observational cohort into analysis rows.
