Method Detail

getDimension

public abstract int getDimension()

Returns the dimension of the hyperparameter vector of the underlying Dirichlet distribution and therefore the dimension of the generated random array.

Returns:

the dimension of the hyperparameter vector of the underlying Dirichlet distribution and therefore the dimension of the generated random array

getHyperparameter

public abstract double getHyperparameter(int i)

Returns the value at position i of the hyperparameter vector of the underlying Dirichlet distribution.

Parameters:

i - the position of the hyperparameter vector

Returns:

the value at position i of the hyperparameter vector of the underlying Dirichlet distribution
