search_optimal_kernel_bandwidth

pysm3.search_optimal_kernel_bandwidth(x, bandwidths: Iterable[float] | None = None) → float

Select KDE bandwidth by leave-one-out log-likelihood grid search.

Parameters:

xarray_like

1D samples (GHz).

bandwidthsiterable of float, optional

Candidate bandwidths to evaluate. If None, a reasonable log-spaced grid is built from the sample standard deviation.

Returns:

float

Best bandwidth (GHz).
