MultivariateGaussian
¶ Represents a (mu, sigma) tuple
Examples
>>> m = MultivariateGaussian(Vectors.dense([11,12]),DenseMatrix(2, 2, (1.0, 3.0, 5.0, 2.0))) >>> (m.mu, m.sigma.toArray()) (DenseVector([11.0, 12.0]), array([[ 1., 5.],[ 3., 2.]])) >>> (m[0], m[1]) (DenseVector([11.0, 12.0]), array([[ 1., 5.],[ 3., 2.]]))
Methods
count
(value, /)Return number of occurrences of value.
index
(value[, start, stop])Return first index of value.
