Statistical Analysis: Model Estimation

LIMDEP and NLOGIT’s model estimation tools for statistical analysis include maximum likelihood estimation, linear and nonlinear least squares, GMM and user specification optimization.

Maximum Likelihood

  • Algorithms: DFP, DFB, BFGS, Newton, BHHH, Steepest Descent
  • Control convergence criteria and maximum iterations
  • Supply starting values or use default
  • Control intermediate technical output
  • Lagrange multiplier statistics computed at starting values

Nonlinear Least Squares and GMM

  • User specified moment conditions
  • Instrumental variables
  • Two step estimation with optimal weighting matrix
  • Random parameters

User specified optimization
