Definitions

In plain terms

For recursive exponential smoothing, older influence typically decays geometrically after initialization effects are accounted for.

Technical

The profile depends on parameterization, adjusted versus recursive form, seed, missing-value policy, and finite history.

Scope

Two smoothers with the same period label need not have the same effective weights.

Examples

  • A governed lesson uses Effective Weight Profile only with declared inputs, timing, parameters, and edge-case behavior.

Common misconceptions

  • Two smoothers with the same period label need not have the same effective weights.
