Linear prediction estimates a signal sample as a weighted sum of previous samples: x-hat[n] equals sum of a_k times x[n-k] over prediction order k. The prediction coefficients are computed by minimizing mean squared prediction error, typically via the Yule-Walker equations solved with Levinson-Durbin recursion. The prediction order (number of coefficients) determines model complexity and spectral resolution. Persistence mechanism: encoded in ITU-T speech codecs (G.729, AMR), embedded in audio analysis toolkits (Praat, librosa), formalized in signal processing textbooks (Rabiner and Schafer, Lyons).

Definition
Why it is in scope
A mathematical technique for estimating future values of a signal as a linear combination of its past samples. Human-made, used in speech coding, audio compression, and spectral estimation. Persisted through standardization in ITU-T codecs, academic textbooks, and DSP engineering practice.
