Confidence intervals for likelihood function parameters

# S3 method for class 'likelihood_function'
confint(object, parm = NULL, level = 0.95,
  ...)

Arguments

object: A likelihood_function object
parm: A character vector of parameter names for which to compute intervals. If NULL, intervals are computed for all parameters.
level: Confidence level (default: 0.95)
...: Additional arguments (unused)

Value

A matrix with two columns containing the lower and upper confidence limits for each parameter. Column names indicate the confidence level.

Details

Uses profile likelihood methodology to construct confidence intervals. The intervals are obtained by finding where the profile log-likelihood drops by \(\chi^2_{1,\alpha}/2\) from its maximum.
