bandwidth" imply a more "squeezed" shape as scale parameter mean in normal
distribution?

the data. The bandwidth determines the degree of smoothness; the larger the
bandwidth, the more smooth the fitting curve.

发帖数: 483 | 3 in nonparametric density estimation, bandwidth refers to the width of the
kernel (such as the gaussian) that is used to build the estimate. The larger
the bandwidth, the coarser the estimate which may corresponds to larger-
scale behaviour of the distribution |
