strategy-mle: Maximum Likelihood Estimation Strategy for FB4 Model

Description

Implements the "mle" FB4 fitting strategy, which estimates the proportion of maximum consumption (p-value) and its uncertainty by maximising the log-normal likelihood of observed final weights. Both an R backend (fit_fb4_mle) and a faster TMB/C++ backend (execute_mle_tmb) are supported. Confidence intervals are derived from the Hessian (delta method) and optionally from a likelihood profile (compute_likelihood_profile).

Arguments

Value

No return value; this page documents the maximum likelihood estimation strategy functions. See individual function documentation for return values.
