| bkde | Returns x and
y coordinates of the binned kernel density
estimate of the probability density of the data. |
| bkde2D | Returns the set of grid points in each coordinate
direction, and the matrix of density estimates over the mesh
induced by the grid points. The kernel is the standard bivariate
normal density. |
| bkfe | Returns an estimate of a binned approximation to the
kernel estimate of the specified density function. The kernel is
the standard normal density. |
| dpih | Uses direct plug-in methodology to select the bin width
of a histogram. |
| dpik | Uses direct plug-in methodology to select the bandwidth
of a kernel density estimate. |
| dpill | Uses direct plug-in methodology to select the bandwidth
of a local linear Gaussian kernel regression estimate. |
| locpoly | Estimates a probability density function, regression
function, or their derivatives using local polynomials. A fast
binned implementation over an equally spaced grid is
used. |
