title: 'profileCI: Profiling a Log-Likelihood to Calculate Confidence Intervals'
version: 1.1.1
doi: 10.32614/CRAN.package.profileCI
abstract: Provides tools for profiling a user-supplied log-likelihood function to
  calculate confidence intervals for model parameters. Speed of computation can be
  improved by adjusting the step sizes in the profiling and/or starting the profiling
  from limits based on the approximate large sample normal distribution for the maximum
  likelihood estimator of a parameter. The accuracy of the limits can be set by the
  user. A plot method visualises the log-likelihood and confidence interval. Cases
  where the profile log-likelihood flattens above the value at which a confidence
  limit is defined can be handled, leading to a limit at plus or minus infinity. Disjoint
  confidence intervals will not be found.
