opt.beta.lim: Find simultaneous confidence intervals for diet proportions...

In QFASA: Quantitative Fatty Acid Signature Analysis

Find simultaneous confidence intervals for diet proportions of a single prey species i.e. solve f(pio) = PVAL(pio) = alpha1. Calls root finding function root.beta.

Description

Find simultaneous confidence intervals for diet proportions of a single prey species i.e. solve f(pio) = PVAL(pio) = alpha1. Calls root finding function root.beta.

Usage

opt.beta.lim(alpha1, par.list, R, p.mat, k)

Arguments

alpha1	simultaneous confidence level
par.list	a list of R.p lists of I beta distribution parameters phi and theta that define diet proportion estimates for each of the prey species. Effectively R.p beta distributions for each of the I prey species from which we bootstrap to calculate p-values.
R	number of bootstrap replicates to use in p-value estimation.
p.mat	predator diet estimates.
k	prey species index 1...I

Value

upper and lower limits simultaneous intervals respectively.
