MultithreadedRNG.noncentral_f(dfnum: Number, dfden: Number, nonc: Number, size: int | tuple | None = None) → ndarray | Number[source]

Draw from a noncentral F distribution.

Parameters:

  • dfnum – Degrees of freedom in numerator, must be > 0.

  • dfden – Degrees of freedom in denominator, must be > 0.

  • nonc – Non-centrality parameter, the sum of the squares of the numerator means, must be >= 0.

  • size – Output shape.

Returns:

numpy.ndarray or scalar.
