Description Usage Arguments Value
It computes a bivariate kernel deconvolution estimator using the Fast Fourier transform (FFT) on a grid.
1 2 |
resol |
An integer specifying the grid size on each coordinate. Power of two are faster. |
samp |
2-column matrix with the contaminated sample. |
error |
Matrix with 2 columns, either with the pure sample of the error, or with the |
truncate |
NULL by default. If the approximated characteristic function of the error is smaller than truncate, it will make the integrand zero. This provides numerical stability. |
h |
Bivariate vector with the bandwidth parameters. |
EMethod |
Method used to approximate the characteristic function of the error. 1 or 2 if ecf of the char. fnc. of the kde is used, respectively. differences obtained from the panel data structure. It can also accept "ecf" or "kde" respectively. |
columns |
Number of columns of the panel data. If there is one column, it assumes that instead panel data, a pure sample of the error is provided. |
Kkernel |
Kernel to be used. See 'ker' function. |
coord1Range |
A bivariate vector with the limits of first coordinate of the grid to estimate the density. |
coord2Range |
A bivariate vector with the limits of second coordinate of the grid to estimate the density. |
sigE |
Bandwidth (2x2) matrix for the error. It is NULL by default and it is required only when EMethod = 2. |
pstve |
TRUE/FALSE determining whether returning zero for those points where the estimate in negative. |
x1 |
Vector of size resol with the first coordinate grid. |
x2 |
Vector of size resol with the second coordinate grid. |
z |
resol x resol grid with the estimated values. |
