tombuch 0 #3 August 22, 2005 The free abstract is interesting, and the article probably is too. However, it looks like the sample used in this paper is limited to fatalities in Sweeden. My copy of the IPC Safety Survey (2000) shows that between 1963 and 2000 Sweeden only had 36 total fatalities with an average of less than 1 per year. In the five year period from 1996 - 2000 they reported only 2 fatalities with a total of just 544,727 jumps. Any single fatality in a sample this small will skew the data. A larger sample would yield a better representation and more accurate data. Sweedish data just isn't large enough to tell us much.Tom Buchanan Instructor Emeritus Comm Pilot MSEL,G Author: JUMP!

From an actuarial perspective, one would say that it isn't "credible" or has low credibility. What one might do is to figure out sometype of standard for "full credibility" (e.g. x # of incidents/accidents in an n-yr time period), calculate the same rate/metric for the full standard or credibility complement (i.e. fatality/incident rate for US/World results), figure out the,....oh nevermind this is getting too complicated to explain and too academic.

Yes, the sample is small, but there's still a lot of intersting facts to be learned from it. So far, I haven't read anything better or more accurate on the subject. /O.J Quote Share this post Link to post Share on other sites
