摘要

Purpose: This project demonstrates how to calibrate different samples and scales of genomic information to a common scale of genomic measurement. Materials and Methods: 1,113 persons were genotyped at the 13 Combined DNA Index System (CODIS) short tandem repeat (STR) marker loci used by the Federal Bureau of Investigation (FBI) for human identity testing. A measurement model of form ln[(P_(nik))/(1-P_(nik)] = B_n - D_i-L_k is used to construct person measures and locus calibrations from information contained in the CODIS database. Winsteps~(TM) (Wright and Linacre, 2003) is employed to maximize initial estimates and to investigate the necessity and sufficiency of different rating classification schema. Results: Model fit is satisfactory in all analyses. Study outcomes are found in Tables 1-6. Conclusions: Additive, divisible, and interchangeable measures and calibrations can be created from raw genomic information that transcend sample- and scale-dependencies associated with racial and ethnic descent, chromosomal location, and locus-specific allele expansion structures.
