statsmodels.sandbox.regression.gmm.NonlinearIVGMM.fitgmm_cu

NonlinearIVGMM.fitgmm_cu(start, optim_method='bfgs', optim_args=None)

estimate parameters using continuously updating GMM

Parameters:	start : array_like starting values for minimization
Returns:	paramest : array estimated parameters

Notes

todo: add fixed parameter option, not here ???

uses scipy.optimize.fmin
