Development of Two Probability Distributions to Analyze Impact Injury Data

摘要

Impact injury data are not, in general, suitable for statistical analysis by least squares, because the data are not observations from normal probability distributions. The principle of maximum likelihood can be used as an alternative, but requires that the appropriate probability distribution be specified. Two appropriate distributions are developed, one for thoracic fractures and another for the Abbreviated Injury Scale. A data sample for each of these two types of data is analyzed by the principle of maximum likelihood in conjuction with the appropriate probability distribution.
