gemclus.data.multivariate_student_t

gemclus.data.multivariate_student_t(n, loc, scale, df=10, random_state=None) → ndarray

Draws \(n\) samples from a multivariate Student-t distribution.

Parameters:

n: int

The number of samples to draw from the distribution.

loc: ndarray of shape (d,)

The position of the distribution to sample from.

scale: ndarray of shape (d,d)

Positive semi-definite scale matrix.

df: int, default=10

Degrees of freedom of the distribution. Controls the spread of the samples.

random_state: int, RandomState instance or None, default=None

Determines random number generation for dataset creation. Pass an int for reproducible output across multiple runs.

Returns:

X: ndarray of shape (n,d)

The samples drawn from the Student-t distribution.
