qLow

qUpp

The confidence level; i.e. the desired coverage is 1-alpha. Defaults to 0.05.

alpha

A single number &gt; 0, giving the initial parameter value to start the optimisation; defaults to 5.

initPars

Maximum number of iterations for <code>optim</code>. Defaults to 1e3. Set to higher values if convergence problems are reported.

maxiter

Finds the best-fit Poisson distribution parameters for a given confidence interval and returns the rate parameter.

Propagate uncertainty from several estimates when combining these estimates via a function.
This is done by using the parametric bootstrap to simulate values from the distribution of each estimate to build up an empirical distribution of the combined parameter.
Finally either the percentile method is used or the highest density interval is chosen to derive a confidence interval for the combined parameter with the desired coverage.
Gaussian copulas are used for when parameters are assumed to be dependent / correlated.
