An Evaluation Method of Ballistic Consistency under Small Sample Circumstance

doi:10.3969/j.issn.1000-1093.2014.12.028

Abstract

Abstract: In order to evaluate ballistic consistency under small sample circumstance, an evaluation method of ballistic consistency is proposed based on the normal distribution small sample compatibility theory. This method is to compare the calculated order statistics and the simulated critical value to determine the ballistic consistency. The main advantage is not necessary to calculate the position- scale estimate value, so it could decrease the calculation error due to small sample size. The calculation shows that this method is better than matched pair t test and probability circle sequential test under small sample circumstance (n≤5).

Key words: ordnance science and technology, ballistic test, ballistic consistency, small sample size, compatibility, evaluation method
