Bootstrap and plug-in bandwidth selectors for kernel density estimation with binned data.
1 2 3 4 |
n |
Positive integer. Size of the complete sample. |
y |
Vector. Observed values. They define the extremes of the sequence of intervals in which data is binned. |
w |
Vector. Proportion of observations within each interval. |
ni |
Vector. Number of observations within each interval. |
gboot |
Positive real number. Pilot bandwidth for the bootstrap bandwidth selector. |
pilot.type |
1, 2 or 3. If |
hn |
Positive integer. Size of the grid of bandwidths for which MISE will be approximated. Defaults to 100. |
plugin.type |
Character. If |
confband |
Logical. If TRUE, bootstrap confidence bands are constructed for the density function. Defaults to FALSE. |
alpha |
Real number between 0 and 1. Significance level for the bootstrap confidence bands. Defaults to 0.05. |
B |
Positive integer. Number of bootstrap resamples used when constructing confidence bands. Defaults to 1000. |
plot |
Logical. If TRUE, kernel density estimators are plotted along with (optional) bootstrap confidence bands. Defaults to TRUE. |
print |
Logical. If TRUE and confband is TRUE, the percentage of bootstrap resamples already evaluated is printed. Defaults to TRUE. |
model |
Character. Name of the parametric family of distributions to be fitted for the grouped sample. Parameters are estimated by maximum likelihood. |
parallel |
Logical. If TRUE, confidence bands are estimated using parallel computing with sockets. |
pars |
Environment. Needed for the well functioning of the script. DO NOT modify this argument. |
If pilot.type
= 1, an heuristic rule is used for calculating the pilot bandwidth. It's not recommended when population's density function is suspected to be highly multimodal.
If pilot.type
= 2, the pilot bandwidth is such that the kernel density estimator with bandwidth gboot
approximates the histogram of the grouped sample minimizing the residual sum of squares. If pilot.type
= 3, a penalty is imposed on the curvature of the kernel density estimator with bandwidth gboot
. The penalty parameter is selected as to best approximate the curvature of the true density.
