fieller.calculate.me R Documentation
Constructs Fieller's confidence interval.
Description
Constructs Fieller's confidence interval - closed form, not using perturbation.
Usage
fieller.calculate.me(a, B, var.mat)
Arguments
a
value of numerator
B
value of denominator
var.mat
variance-covariance matrix for a and B
Details
Produces a confidence interval for 1-a/B when closed form variance and covariance estimates are available. See documention for R.s.estimate.me for more detail.
Value
Returns a vector of length 2, lower bound of the 95% confidence interval and upper bound of the 95% confidence interval.
