Parameters
Parameters 
Description 
p 
Probability, real positive value on closed interval [0,1]. 
m 
Location parameter, real value. 
b 
Shape parameter, real positive value. 
Returns

the Cauchy distribution point percent function (PPF) for given parameters b and m.

Description

The inverse Cauchy cumulative distribution function is defined by the following equation: 

 

The result of CauchyCDFInv is the solution of the integral equation of the Cauchy CDF with parameters b and m and with the desired probability p.
