class reliability.Convert_data.FNRN_to_FR(failures, num_failures, right_censored=None, num_right_censored=None)

Converts data from FNRN format to FR format

Parameters:

• failures (array, list) – The failure times
• num_failures (array, list) – The number of failures are each failure time. Length must match length of failures.
• right_censored (array, list, optional) – The right censored times
• num_right_censored (array, list, optional) – The number of values at each right_censored time. Length must match length of right_censored.

Returns:

• failures (array) – The failure times
• right_censored (array) – The right censored times

Notes

Example usage:

FR = FNRN_to_FR(failures=[1,2,3], num_failures=[1,1,2], right_censored=[9,8,7], num_right_censored=[5,4,4])
print(FR.failures)
    >>> [1. 2. 3. 3.]
print(FR.right_censored)
   >>> [9. 9. 9. 9. 9. 8. 8. 8. 8. 7. 7. 7. 7.]
FR.print()
   >>>  Data (FR format)
