Feature
f__last_digit contains the last digit (modulus of 10) of the response to all questions of type NumericQuestion in the microdata.
Rationale
Unusual distribution of last digits can be indicative of e.g. :
- interviewers inadvertently rounding to 5 or 10
- interviewers confusing the units, e.g. forgetting to record the thousands in monetary questions (e.g. record 3 instead of 3,000)
