Sequential Testing And Peeking Correction Calculator
Sequential Testing And Peeking Correction: a planned Super Calculator tool. Stub page: the tool, its formula and a worked example are not published yet.
Sequential Testing And Peeking Correction Calculator is a planned calculator in the mathematics section of Super Calculator, covering experimentation and A/B testing.
What this calculator will compute
Inputs: planned looks, total alpha, spending function shape and observed statistics at each look.
Outputs: boundary values per look, adjusted p value, stopping decision and alpha spent to date.
Formula, recorded as scope and not yet verified against a primary source: Group sequential boundaries by the Lan-DeMets alpha spending function with an O’Brien-Fleming or Pocock shape, or always-valid inference via a mixture sequential probability ratio test. Both control the family-wise type I error across repeated interim looks.
