identifyPoisPars {bootComb}

Determine the parameters of the best-fit Poisson distribution for a given confidence interval.

Description

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

Usage

identifyPoisPars(qLow, qUpp, alpha = 0.05, initPars = 5, maxiter = 1000)

Arguments

qLow

The observed lower quantile.

qUpp

The observed upper quantile.

alpha

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

initPars

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

maxiter

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

Value

A single number giving the rate parameter for use with rpois/dpois/ppois/qpois.
