YZ: Yan and Zhang (2012) Grid-Search based PIN Estimates

Description

It estimates PIN using Yan and Zhang (2012) algorithm.

Usage

YZ(data, likelihood = c("LK", "EHO"))
# S3 method for YZ_class
print(obj)

Arguments

data

Data frame with 2 variables

likelihood

Character strings for likelihood algorithm. Default is "LK".

obj

object variable

Value

Returns a list of parameter estimates (output)

alpha

A Number

delta

A Number

mu

A Number

eb

A Number

es

A Number

LikVal

A Number

PIN

A Number

Warning

This function does not handle NA values. Therefore the datasets should not contain any missing value

Details

Argument for data must be a data frame with 2 columns that only contain numbers. Not any other type. You do not have to give names to the columns. We will assign first one as "Buy" and second as "Sell", therefore you should put order numbers with respect to this order.
