nzilbb.vowels vs PINstimation: at a glance
What is nzilbb.vowels?
A vowel-analysis package trimming dependencies after an email address got it archived.
nzilbb.vowels supports sociophonetic vowel analysis — principal component analysis over vowel measurements, Procrustes comparison of loadings, and the plotting that goes with them. Three releases are visible, all in the 0.4.x line and all small. The substantive thread is dependency removal: vegan and gghalves have both been dropped in favour of code the package controls.
What is PINstimation?
A market-microstructure toolkit that keeps adding estimators as the papers land.
PINstimation estimates probability-of-informed-trading models — PIN, multilayer PIN, adjusted PIN and VPIN — from trade and quote data, and handles the trade classification and aggregation that feeds them. The current 0.2.0 adds ivpin(), a maximum-likelihood variant of VPIN from Ke and Lin (2017). The package's early history is compressed into a single hour of backfilled tags in October 2022, so version order there does not track release order.

◆ Current state
nzilbb.vowels supports sociophonetic vowel analysis — principal component analysis over vowel measurements, Procrustes comparison of loadings, and the plotting that goes with them. Three releases are visible, all in the 0.4.x line and all small. The substantive thread is dependency removal: vegan and gghalves have both been dropped in favour of code the package controls.
◆ Where it's heading
The package is reducing what it relies on, and paying for it in small interface breaks — plot_correlation_counts() lost its half_violin argument and gained a points argument in the same move. The 0.4.2 notes also record that version 0.4.1 was archived by CRAN because the maintainer's email had become unreliable, prompting a switch to an institutional address. That is administrative rather than technical, but it explains why three closely spaced patches exist at all.
◆ Prediction
With the two external plotting and ordination dependencies gone and the maintainer address stabilised, the visible pressure that produced these releases is resolved. Nothing in the entries indicates what comes next, and the history is too short to read a feature direction from.
PINstimation
0.0INFRA · APIS
A market-microstructure toolkit that keeps adding estimators as the papers land.
◆ Current state
PINstimation estimates probability-of-informed-trading models — PIN, multilayer PIN, adjusted PIN and VPIN — from trade and quote data, and handles the trade classification and aggregation that feeds them. The current 0.2.0 adds ivpin(), a maximum-likelihood variant of VPIN from Ke and Lin (2017). The package's early history is compressed into a single hour of backfilled tags in October 2022, so version order there does not track release order.
◆ Where it's heading
Each release tracks the literature: a Bayesian PIN estimator from Griffin et al., an improved VPIN from Ke and Lin, initial-parameter generation realigned to Ersan and Ghachem. The other steady thread is data handling — matrix inputs so the estimators compose with rolling windows, user-specified aggregation frequencies, and now quote leads as well as lags. The three-year gap between 0.1.2 and 0.2.0 makes this a slow, publication-paced package rather than an actively developed one.
◆ Prediction
On this pattern the next release adds whatever estimator the authors publish next, since two of the three feature releases here implement a specific paper. Nothing in the entries points to a change in the package's structure.
