public interface Distribution
This interface should be implemented by all classes supporting discrete and continuous distributions. It specifies the signature of methods that compute the distribution function F(x), the complementary distribution function bar(F)(x), and the inverse distribution function F-1(u). It also specifies the signature of methods that returns the mean, the variance and the standard deviation.
Method Summary | |
---|---|
double |
barF(double x)
Returns bar(F)(x) = 1 - F(x). |
double |
cdf(double x)
Returns the distribution function F(x). |
double |
getMean()
Returns the mean of the distribution function. |
double[] |
getParams()
Returns the parameters of the distribution function in the same order as in the constructors. |
double |
getStandardDeviation()
Returns the standard deviation of the distribution function. |
double |
getVariance()
Returns the variance of the distribution function. |
double |
inverseF(double u)
Returns the inverse distribution function F-1(u), defined in. |
