Python ContinuousValue.unbiased_mean示例

示例#1

def test_cv_update_batch():
    cv1 = ContinuousValue()
    cv2 = ContinuousValue()
    nums = [random() for i in range(10)]

    for n in nums:
        cv1.update(n)

    cv2.update_batch(nums)

    assert cv1.unbiased_mean() == cv2.unbiased_mean()
    assert cv1.biased_std() == cv2.biased_std()

示例#2

def test_cv_unbiased_mean():
    nums = [random() for i in range(10)]
    cv = ContinuousValue()
    for n in nums:
        cv.update(n)
    assert cv.unbiased_mean() - sum(nums)/len(nums) <= 1e-6
