Well, since you are asking about 'statistically' :

I have a Boeing presentation entitled **['V1 and the Go / No Go Decision'][1]** from 2002

In there it presents the case of Rejected TakeOffs and Overruns out of an estimated **76,000 RTOs** studied between 1958 and 1990 about **74 ended in Overruns**. 56% of them were initiated after V1 (most of them >120kts), and also 56% of them were avoidable completely by continuing the takeoff. 

This puts your statistical chances of a mishap about 0.1% in case of RTO before V1 and about 56% after. If you think you have a better chance in the air, take the flight.
