The Court may, under the "Daubert" ruling, find scientific testimony to be inadmissible for lack of recitation of its bounds of reliability. Take the high ground; use the advanced statistical methods of CRASHEX to be ready to meet ~ and, furthermore, to mount ~ such a challenge. See the DAUBERT AND AR slide show. Then see the RELIABILITY RECONSTRUCTION slide show as used for presentation of the Society of Automotive Engineers paper on Applied Finite Difference Analysis.

COMPUTERIZED RECONSTRUCTION OF APPROACH SPEEDS ON THE HIGHWAY, EXTENDED --  CRASHEX

You are a skilled automobile accident reconstructionist --- but --- can you state the 95% likely span of your best estimate? You should be able to. If not, you are not (so far as the jury is concerned) convincingly expressing your confidence in your own opinion. You may also be failing (so far as the judge is concerned) to satisfy the Daubert "reliability standard." You (and, for that matter, your opponent) should be able and eager to answer this question -- With reasonable engineering certainty, based on the evidence what are the speeds of the vehicles at impact -- AND by how much might they vary from those values?

Nothing is known with certainty, but due to recent research the reliability of every measurement on which your reconstruction is based is known. Given that, there is an elegant statistical method of finding the reliability of your reconstruction. This is done after you have developed your "best case," either within the downloadable program, or after you have completed your analysis using your usual means of reconstruction or simulation. CRASHEX 3.1 provides that method - and You can bill the entire modest usage-based expense directly to your client. NEXT
