%description
A comprehensive bundle of utilities for the estimation of probability of
informed trading models: original PIN in Easley and O'Hara (1992) and
Easley et al. (1996); Multilayer PIN (MPIN) in Ersan (2016); Adjusted PIN
(AdjPIN) in Duarte and Young (2009); and volume-synchronized PIN (VPIN) in
Easley et al. (2011, 2012). Implementations of various estimation methods
suggested in the literature are included. Additional compelling features
comprise posterior probabilities, an implementation of an
expectation-maximization (EM) algorithm, and PIN decomposition into
layers, and into bad/good components. Versatile data simulation tools, and
trade classification algorithms are among the supplementary utilities. The
package provides fast, compact, and precise utilities to tackle the
sophisticated, error-prone, and time-consuming estimation procedure of
informed trading, and this solely using the raw trade-level data.
