PLProblem{T,probType,P,PF,PR}

Defines a profile likelihood problem.

Mathematical Specification of a Profile Likelihood Problem:

A profile likelihood problem is defined by

• an objective function (usually negative log-likelihood function) wrapped within an optprob::OptimizationProblem. Consult Optimization.jl docs for details.
• a set of optimal values of the parameters optpars that minimize the objective function.

Constructors

PLProblem(optprob, optpars, profile_range = tuple.(optprob.lb, optprob.ub); 
  conf_level = 0.95, df = 1, threshold = chi2_quantile(conf_level, df))

Arguments

• optprob: The OptimizationProblem to be solved.
• optpars: Initial (optimal) values of the parameters.
• profile_range: The range over which the profile likelihood is computed. Defaults to tuple.(lb,ub) of the OptimizationProblem.

Keyword arguments

• conf_level: The confidence level for the profile likelihood. Defaults to 0.95.
• df: The degrees of freedom for the profile likelihood. Defaults to 1.
• threshold: The threshold for the profile likelihood. Can be set to Inf if confidence interval endpoint estimation is not required. Defaults to chi2_quantile(conf_level, df).
