statsmodels.nonparametric.kernels_asymmetric.kernel_pdf_beta2(x, sample, bw)

Beta kernel for density, pdf, estimation with boundary corrections.

Parameters:

• x (array_like, float) – Points for which density is evaluated. x can be scalar or 1-dim.

• sample (ndarray, 1-d) – Sample from which kde is computed.

• bw (float) – Bandwidth parameter, there is currently no default value for it.

Return type:

Components for kernel estimation
