Technical Notes: Cohort Retention Calculator

Empirical Reference & Bounds
01.

Why is statistical rigor critical in Cohort Retention Calculator?

Stopping an experiment or scaling budget before reaching statistical significance (|Z| >= 1.96, p < 0.05) leads to Type I false positives and capital loss.

02.

How accurate is the Cohort Retention Calculator for scenario modeling?

This calculator uses exact closed-form algebraic and statistical equations. Use the sensitivity matrix and scenario presets (0.5x, 1.0x, 2.0x) to stress-test variance before committing capital.
