BicopBase.cdf

BicopBase.cdf(u, x=None)

Raise; the vine CDF is Monte-Carlo, so a per-pair cdf is optional.

Parameters:

uarray, shape (n, 2), dtype float

Pair pseudo-observations (unused in the raising default).

xarray, shape (n, k), or None, optional

Conditioning variables (unused in the raising default).

Returns:

array, shape (n,), dtype float

Distribution values — only when a subclass overrides this method.

Raises:

NotImplementedError

Always, unless a subclass provides a native cdf.
