- statsmodels.nonparametric.kernels_asymmetric.kernel_pdf_invgamma(x, sample, bw)[source]¶
Inverse gamma kernel for density, pdf, estimation.
Based on cdf kernel by Micheaux and Ouimet (2020)
- Parameters:
- xarray_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.
- xarray_like,
- Returns:
