Parametric Analysis

Descriptive stats, not semantics.

Standard metrics

• Per document: word count, sentence count, avg word length, avg sentence length, unique-token ratio (type-token ratio), reading-ease score (Flesch, Flesch-Kincaid grade).
• Corpus-wide: total docs, total tokens, vocabulary size, Zipf distribution, stopword ratio, punctuation density.
• Distributions: histograms of doc length (tokens, words, sentences), percentiles (p10/p50/p90/p99).
• Lexical diversity: MTLD or MATTR (better than raw TTR which is length-sensitive).
