fitgmm
(start, weights=None, optim_method=None, **kwds)[source]¶ estimate parameters using GMM for linear model
Uses closed form expression instead of nonlinear optimizers
- Parameters
- start
not
used
starting values for minimization, not used, only for consistency of method signature
- weights
array
weighting matrix for moment conditions. If weights is None, then the identity matrix is used
- optim_method
not
used, optimization method, not used, only for consistency of method signature
- **kwds
keyword
arguments
not used, will be silently ignored (for compatibility with generic)
