Fit a kernel density estimate using FFT-based KDE with Improved Sheather-Jones bandwidth selection.

import numpy as np from KDEpy import FFTKDE # Generate sample data np.random.seed(123) data = np.random.normal(0, 1, size=100) # Fit KDE kde = FFTKDE(bw='ISJ') x, y = kde.fit(data).evaluate(1024) # Plot import matplotlib.pyplot as plt plt.plot(x, y) plt.show()

Debug

Known issues

gotchaThe import path uses mixed case: `from KDEpy import ...`. Lowercase `from kdepy import ...` will fail.

fix

Use uppercase KDE in the import statement.

affects: all

gotchaThe Bandwidth class is not exposed in the top-level namespace. Users may mistakenly attempt to import it directly from KDEpy.

fix

Use `from KDEpy.bandwidth import Bandwidth` or rely on automatic bandwidth selection via `bw` parameter.

affects: all

gotchaIn KDEpy, the default bandwidth selection method changed between versions. In v1.1.0+, the default for FFTKDE is 'ISJ' (Improved Sheather-Jones) instead of 'silverman'.

fix

Explicitly specify `bw='silverman'` if you need the old default.

affects: >=1.1.0

deprecatedThe `bw_method` keyword argument was deprecated in v1.0.0 in favor of `bw`.

fix

Use `bw` instead of `bw_method`.

affects: >=1.0.0
