Usage REAL X,A,B,Y

Y=FNQ_cauchy(A,B,X)

Description

FNQ_cauchy returns the value of the complementary integral of the Cauchy probability density function with parameters a and b. This integral, Q(x;a,b), is defined by the expression

which reduces to

B must be greater than zero.

Q(x;0,b)

Errors

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