• num_failures (array) – The number of failures are each failure time
• right_censored (array) – The right censored times
• num_right_censored (array) – The number of values at each right_censored time

Notes

Example usage:

FNRN = FR_to_FNRN(failures=[1,1,2,2,3], right_censored=[9,9,9,9,8,8,7])
print(FNRN.failures)
    >>> [1 2 3]
print(FNRN.num_failures)
    >>> [2 2 1]
print(FNRN.right_censored)
   >>> [7 8 9]
print(FNRN.num_right_censored)
   >>> [1 2 4]
FNRN.print()
   >>> Data (FNRN format)
