TRANSFERWISE
TransferWise (TW) is an international money transfer platform. It makes it up to 10 times cheaper to send money abroad compared to using similar services offered by banks. TW’s technology is based on peer-to-peer system and has helped customers to move more than £4,5bn – an approach that has saved customers£180m.

TIME SERIES ANALYSIS
A time series is a collection of observations of well-defined data items obtained through repeated measurements over time.

THE OUTCOME
23
THE PROPOSED NEXT STEPS 1. Include more factors into
calculational model 2. Enhance the proposal
algorithm 3. Carry out tests and compare
the efficiency vs. current human factor
4. Based on results decide whether more determinants need implementing
5. If needed, repeat steps 1,2,3 6. Go live 7. Continuously improve the
solution
PLAN: WHAT TO DO NEXT

QUESTION FROM REVIEWER
Q: Kuidas suhtute mõttesse, eemaldada andmetest põhitrendid ja siis katsetada jääki juhuslikkusele ja alles seejärel tuua sisse lisafaktoreid? How do you find the idea of removing main trends from data and test the irregular component and only then introduce extra factors. (perform seasonal adjustment)? A: Aegridade teooria järgi oleks selline lähenemine õige, aga kuna seadsin antud tööle järgneva tuleviku väljavaateks just olulisemate ettevõtteväliste ja sisemiste sesoonsusest sõltumatute lisafaktorite mõju uurimise ja vähendamise, siis põhitrendide analüüsi jätsin teadlikult kõrvale. According to the theory of time series, such approach is correct. I have set a goal for future development after this thesis to mitigate the impact of main internal and external determinants that are independent from seasonalities. For that reason I decided not to perform classical seasonal adjustment.
