Nine working papers are presented as the result of a study to develop a statistical methodology and formulation of specific statistical procedures for the analysis of in-use automobile fuel-economy data. Topics covered are: (1) variance computed relative to the harmonic mean; (2) bases for statistical estimation of fuel economy; (3) estimating the standard error for a sample harmonic mean; (4) the effect of accumulated odometer miles on mpg shortfalls; (5) aggregation of data from sources with groups of ''replicate'' vehicles; (6) philosophical and analytic issues affecting the FEA fuel-economy study; (7) a regression/covariance analysis approach to estimation of fuel economy; (8) vehicle ranking according to fuel economy; and (9) a regression approach to vehicle ranking.
