This article describes some approaches to imitation analysis and the use of ready-made software for this task.

The article describes some approaches to imitation analysis and the use of ready-made software to assess the effectiveness of stylistic imitation of eighteenth-century historical chronicle in La renuncia del héroe Baltasar (The Renunciation of the Hero Baltasar), by the Puerto Rican novelist Rodríguez Juliá. Even when employing familiar procedures of text analysis with computer, comparing a fictional text with a multiple and diverse corpus of authentic historical documents requires somewhat unique assumptions and hypotheses, since neither authorship, influence, or authenticity are in question.
