Probability density for Cauchy distribution.

Loading LOADSUB ALL FROM "CAUCHY.HTS"

or LOADSUB FROM "MATHLIB.HTS"

Usage REAL X,A,B,Y

Y=FNF_cauchy(A,B,X)

Description

FNF_cauchy returns the value of the probability density function of the Cauchy distribution with parameters a and b at x. This density, f(x;a,b), is defined by the expression

B must be greater than zero.

f(x;a,b)

Errors

FNF_cauchy causes an HTBasic error if its arguments are not all of type REAL or if b is negative or zero.
