From:"Bachman, William" Subject:RE: [NMusers] CV Date:Tue, 4 Feb 2003 13:27:29 -0500 The expression for CV is dependent on the parameterization of the error model. If the error model is proportional, e.g. V = TVV+ TVV*ETA(n) (or the exponential equivalent, V = TVV * EXP(ETA(n)) ) then the CV = sqrt(omega(n))*100 If the error model is additive, eg. V= TVV+ETA(n), then the CV becomes CV = sqrt(omega(n))/theta(n) * 100 in both cases omega(n) is the variance of ETA(n) and theta(n) is the population estimate of the parameter (mean). nmconsult@globomaxnm.com GloboMax LLC 7250 Parkway Drive, Suite 430 Hanover, MD 21076 Voice: (410) 782-2205 FAX: (410) 712-0737
