Kde1d.from_params

Kde1d.from_params(xmin: float | None = None, xmax: float | None = None, type: str = 'continuous', multiplier: float = 1.0, bandwidth: float | None = None, degree: int = 2, grid_size: int = 400) → pyvinecopulib.Kde1d

Create a Kde1d object from parameters.

This is a factory method that creates a Kde1d object with specified parameters. The object needs to be fitted to data using the fit() method.

Parameters:

  • xmin (float, optional) – Lower bound for the support of the density. Default is NaN.

  • xmax (float, optional) – Upper bound for the support of the density. Default is NaN.

  • type (str, optional) – Variable type ("continuous", "discrete", or "zero_inflated"). Default is "continuous".

  • multiplier (float, optional) – Bandwidth multiplier. Default is 1.0.

  • bandwidth (float, optional) – Bandwidth parameter (NaN for automatic selection). Default is NaN.

  • degree (int, optional) – Degree of the local polynomial (0, 1, or 2). Default is 2.

  • grid_size (int, optional) – Number of grid points for the interpolation grid. Must be at least 4. Default is 400.

Returns:

Kde1d – A Kde1d object ready for fitting.
