sents the
    collection of uncensored and left-censored values.

Examples
--------
>>> from scipy.stats import CensoredData

Two uncensored values (0.12 and 0.033) and two left-censored values
(both 1e-3).

>>> data = CensoredData.left_censored([0.12, 0.033, 1e-3, 1e-3],
...                                   [False, False, True, True])
>>> data
CensoredData(uncensored=array([0.12 , 0.033]),
left=array([0.001, 0.001]), right=array([], dtype=float64),
interval=array([], shape=(0, 2), dtype=float64))
>>> print(data)
CensoredData(4 values: 2 not censored, 2 left-censored)
)
