WebMar 23, 2012 · The VPIN Metric and the Estimation of Parameters The standard approach to computing the PIN model uses maximum likelihood to estimate the unobservable parameters (α, μ, δ, ɛ) driving the stochastic process of trades and then derives PIN from these parameter estimates. WebJan 1, 2014 · The VPIN metric is based on a model of time-varying arrival rates of informed and uninformed traders developed in Easley, Engle, O’Hara, and Wu (2008). The derivation of VPIN was introduced first in Easley, Lopez de Prado, and O’Hara (ELO) (2011a) and is developed most completely in ELO (2012a). WebDec 30, 2011 · The details are discussed in Easley et al. (1996), among others.

WebDec 12, 2024 · As Easley, Prado and O’Hara (2012) realized that CDF of VPIN is a better indicator than actual VPIN itself, we also compared the CDF of VPIN at different exchanges and for different stocks. We decided to calculate average rolling correlation of CDF across the exchanges and across the stocks.
