In jknape/poptrend: Estimate Smooth and Linear Trends from Population Count Survey Data
hessBootstrap R Documentation
Compute bootstrap confidence intervals based on sampling from the variance-covariance matrix.
Description
Draws bootstrap samples using the estimated variance matrix of the fitted gam model.
Usage
hessBootstrap(trend, nBoot = 500)
Arguments
trend
An object of class trend.
nBoot
The number of bootstrap samples to draw.
Details
This function is used by ptrend and would typically not be called directly.
Bootstrap samples are drawn using the estimated coefficients and covariance matrix vcov.gam
of the fitted gam model. The default values of vcov.gam which gives the Bayesian posterior
covariance matrix.
Bootstrapped samples computed in this way do not account for any uncertainty in the selection of degrees
of freedom.
Value
A trend object with the bootstrapped trend estimates appended.
