4 Dendrogram of authorship for five novelists (data and figure courtesy of David Hoover). that this additional information can be helpful in arriving at methods of categorization. 1 Simple Statistics The simplest form of supervised analysis, used since the 1800s, is simple descriptive statistics. For example, given a set of documents from two different authors, we can easily calculate word lengths  and (handwaving a few statistical assumptions) apply t-tests to determine whether the two authors have different means.

1 Vector Spaces and PCA With the feature structure defined in the previous section, it should be apparent how documents can be described in terms of collections of features; quantifying the features, in turn, will implicitly create a high-dimensional “document space” with each document’s feature set defining a vector or a point in that space. For example, the token frequency of fifty well-chosen words defines a fifty-place vector for each document (some normalization would probably be necessary).
