linearmodels.iv.model._OLS.estimate_parameters¶

static _OLS.estimate_parameters(x: ndarray, y: ndarray, z: ndarray, kappa: int | float) → ndarray¶

Parameter estimation without error checking

Parameters:¶

x: ndarray¶

Regressor matrix (nobs by nvar)

y: ndarray¶

Regressand matrix (nobs by 1)

z: ndarray¶

Instrument matrix (nobs by ninstr)

kappa: int | float¶

Parameter value for k-class estimator

Returns:¶

Estimated parameters (nvar by 1)

Return type:¶

numpy.ndarray

Notes

Exposed as a static method to facilitate estimation with other data, e.g., bootstrapped samples. Performs no error checking.
