public static double regularizedBeta(double x,
double a,
double b)
throws MathException
x - the value.a - the a parameter.b - the b parameter.
MathException - if the algorithm fails to converge.
public static double regularizedBeta(double x,
double a,
double b,
double epsilon)
throws MathException
x - the value.a - the a parameter.b - the b parameter.epsilon - When the absolute value of the nth item in the
series is less than epsilon the approximation ceases
to calculate further elements in the series.
MathException - if the algorithm fails to converge.
public static double regularizedBeta(double x,
double a,
double b,
int maxIterations)
throws MathException
x - the value.a - the a parameter.b - the b parameter.maxIterations - Maximum number of "iterations" to complete.
MathException - if the algorithm fails to converge.
