Abstract Suppose observations y 1,…, yn stem from a parametric model f (y, θ), with the
parameter taking one value θ L for y 1,…, y τ and another value θ R for y τ+ 1,…, y n. This …

It is typical in stylometry to assume that authors have a unique writing style which is common
to all their published writings and is constant over time. Based on this assumption, statistical …

In the study of ancient literature, a major problem is to deal with uncertain authorship.
Ambiguity about authorship is not limited to the works from remote era. Different reasons …

To help settle the debate around the authorship of Tirant lo Blanc, we analyse the evolution
of the diversity of the vocabulary used in that book, as measured through eight different …

Time-series data often have an abrupt structure change at an unknown location. This paper
proposes a new statistic to test the existence of a change-point in a multinomial sequence …

We proposed statistical analysis of the heterogeneity of literary style in a set of texts that
simultaneously use different stylometric characteristics, like word length and the frequency of …

Tirant lo Blanc (TLB) is a masterpiece of medieval Catalan chivalric romance. Regarding its
authorship, two hypotheses exist: the single-authorship hypothesis claims in agreement with …

Given the output of a data source taking values in a finite alphabet, we wish to detect change-
points, that is times when the statistical properties of the source change. Motivated by ideas …

The detection of outlying rows in a contingency table is tackled from a Bayesian perspective,
by adapting the framework adopted by Box and Tiao for normal models to multinomial …
