Quantifying the Relationship between AMC Resources and U.S. Army Materiel Readiness

The attached report summarizes the results of an AMC study which tests correlation and linear regression analysis as a means to quantify the relationship between AMC resources and U.S. Army materiel readiness. The independent variables chosen were actual obligations of selected AMC procurement and Operations and Maintenance resources the dependent variables chosen were reported materiel readiness measures. Separate analyses were conducted for each materiel commodity group -- aircraft, missiles, combat vehicles, artillery weapons and armaments, tactical and support vehicles, communications and electronics equipment, and other support equipment. For each commodity group, obligations of each selected resource category were paired with each of the reported readiness measures on quarterly frequency first quarter FY81 through fourth quarter FY88 to calculated a coefficient of correlation and a linear regression line. The results, although inconclusive, question the utility of linear regression as a tool for determining the effects of expenditure on materiel readiness.
