WebJul 25, 2016 · Bandwidth selection strongly influences the estimate obtained from the KDE (much more so than the actual shape of the kernel). Bandwidth selection can be done by a “rule of thumb”, by cross-validation, by “plug-in methods” or by other means; see , for reviews. gaussian_kde uses a rule of thumb, the default is Scott’s Rule. WebThe corresponding area within this FWHM accounts to approximately 76%. The width does not depend on the expected value x 0; it is invariant under translations.If the FWHM of a Gaussian function is known, then it can be integrated by simple multiplication..
