# scikits.statsmodels.sandbox.sysreg.SUR.fit

`SUR.``fit`(igls=False, tol=1.0000000000000001e-005, maxiter=100)
  igls : bool
    Iterate until estimates converge if sigma is None instead of two-step GLS, which is the default is sigma is None.

  tol : float

  maxiter : int

  Notes

  This ia naive implementation that does not exploit the block diagonal structure. It should work for ill-conditioned sigma but this is untested.
