bisect.beta.lim: Find simultaneous and individual confidence intervals for...
In QFASA: Quantitative Fatty Acid Signature Analysis
bisect.beta.lim R Documentation
Find simultaneous and individual confidence intervals for diet
proportions of a single prey species i.e. solve f(pio) = PVAL(pio)
= alpha1 and f(pio) = PVAL(pio) = alpha2 using bisection.
Description
Assumptions: alpha1 < alpha2
Usage
bisect.beta.lim(alpha1, alpha2, par.list, R, p.mat, k)
Arguments
alpha1
simultaneous confidence level
alpha2
individual 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 distibutions 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
Details
Note: Tried to minimize number of times have to compute a pvalue
since very slow.
Value
upper and lower limits for individual and simultaneous
intervals respectively.
