Python KalmanFilter.initialize_approximate_diffuse示例

示例#1

文件： test_representation.py 项目： zhaowill/statsmodels

def test_no_endog():
    # Test for RuntimeError when no endog is provided by the time filtering
    # is initialized.

    mod = KalmanFilter(k_endog=1, k_states=1)

    # directly call the _initialize_filter function
    assert_raises(RuntimeError, mod._initialize_filter)
    # indirectly call it through filtering
    mod.initialize_approximate_diffuse()
    assert_raises(RuntimeError, mod.filter)
