Distinguish log-odds interaction from risk-difference contrasts using an explicit four-scenario prediction grid.
Reconcile Risk Sets at Each Survival Event Time
Check event-time denominators, censoring order, and entries before interpreting a product-limit survival calculation.
Define Competing Events Before Estimating Event Probability
Separate the first-event question from censoring and choose a probability summary that matches the endpoint.
Report Monte Carlo Precision for Simulated Probabilities
Distinguish simulation repetitions from study sample size and quantify uncertainty in estimated coverage or rejection rates.
Transform Means and Spread Under an Affine Conversion
Apply offsets to location and scale factors to variability while preserving interval ordering and covariance meaning.
Bound a Binary Risk Difference Under Missing Outcomes
Explore extreme event assignments without mistaking logical bounds for a confidence interval or an imputation recommendation.
