simex

Vector of the response value for each site.

Vector of the set of values at which the CDF is estimated.

sigma

Variance of the estimated measurement error variance.

var.sigma

Logical value that indicates whether the survey design
utilizes two stages.

cluster.ind

Vector of the stage one sampling unit (primary sampling unit
or cluster) code for each site.

cluster

This function executes the extrapolation step of the simulation extrapolation
deconvolution method (Stefanski and Bay, 1996). The function can accomodate
single-stage and two-stage samples.

These functions provide procedures for selecting sites for spatial
surveys using spatially balanced algorithms applied to discrete points,
linear networks, or polygons. The probability survey designs available
include independent random samples, stratified random samples, and unequal
probability random samples (categorical or probability proportional to
size). Design-based estimation based on the results from surveys is
available for estimating totals, means, quantiles, CDFs, and linear models.
The analyses rely on package survey for most results. Variance estimation
options include a local neighborhood variance estimator that is appropriate
for spatially-balanced survey designs. A reference for the survey design
portion of the package is: D. L. Stevens, Jr. and A. R. Olsen (2004),
