Measure of durational variability of events

Description

This function calculates of durational variability of events (nPVI).

Usage

periodicity_nPVI(df = NULL, instr = NULL)

Arguments

df	data frame to be processed (required)
instr	Instrument to be processed (required)

Details

This measure is borne out of language research. It has been noted that the variability of vowel duration is greater in stress- vs. syllable-timed languages (Grabe & Low, 2002). This measure accounts for the variability of durations and is also called "normalized Pairwise Variability Index" (nPVI). Patel & Daniele have applied it to music (2003) by comparing whether the prosody of different languages is also reflected in music. There is a clear difference between a sample of works by French and English composers.

Value
