Extract

The most widespread and best-known use of computers in stylistic analysis has been in the attempts to resolve questions of disputed authorship. Here, the computer's ability to store the whole known corpus of an author's work and to compare it with the disputed work in many ways which would be inexpressibly tedious, if not impossibly lengthy, by hand, is an invaluable aid. Many studies have been carried out on classical texts where the authorship is doubtful, but these studies have most often had undisputed texts against which a disputed work could be compared. The Historia Augusta presents a different situation: there are six ‘authors’ to whom varying amounts of the work are assigned.

5 The calulation is as follows: subtract the mean of one text from the mean of another; then, for each of these texts, take the square of the standard deviation and divide this by the number of items, and add these two values together; finally, take the square of this sum to give the standard error of dffference between the means.
