Methods for the Statistical Analysis of Narrative Texts

Abstract

The coefficient d(X,Y) permitting us to estimate quantitatively the stability of the maximum principle relative to original data perturbations was introduced in Part 1, Ch. 2, § 4. We give here a short description of it, and recall the basic related concepts. Let t ₁(X), ..., t _p (X) be the years in the time interval (A, B) in which the volume graph for a narrative text X exhibits splashes (= spikes or peaks). Suppose that the vector T(X) = (t ₁(X), ..., t _p (X)) is related to the “authentic event” vector T(A, B) where (A, B) is the period described in the text.
