If you are a student and want your paper to be considered for student paper competition, then ask your supervisor to send a mail at statfin@cmi.ac.in, with a particular mention that you were the primary contributor and author of the paper, by Oct 10, 2018.
You must submit your paper by Oct 10, 2018, to be considered for the competition.
It is a good practice to arXiv your paper and during the submission you just share the link of the paper.
