Figure 4.6.1: Dutch Literary novels written by female authors (1)
Principal components analysis (100 most frequent words). Measure: PCA, correlation version.
Figure 4.6.1 presents a principal component analysis of the 100 most frequent words, and the graph below shows which words play a role in this analysis. The ‘loadings’ - which words are remarkably more frequent in which books compared to the others - do not help much further here; it does become clear that the differences are in very common words such as prepositions and adverbs, and perhaps in the predominant narrative tense in the novels (past tense versus present tense).
