An Algorithm for FIML and 3SLS Estimation of Large Nonlinear Models

This paper presents a numerical algorithm for computing full information maximum likelihood (FIML) and nonlinear three-stage least squares (3SLS) coefficient estimates for large nonlinear macroeconomic models. The new algorithm, which is demonstrated by actually computing FIML and 3SLS coefficient estimates for two versions of the 97 equation Fair Model, is substantially more effective than other algorithms on FIML and 3SLS estimation problems.
