Most likely, the model that you refer looks similar to
CL=THETA*EXP(ETA)
For the FO method, this is equivalent to
CL=THETA*(1+ETA)
Variance of CL is THETA^2*OMEGA where OMEGA is the variance of ETA
Standard deviation of CL is THETA*SQRT(OMEGA)
Mean of CL is THETA
CV = SD/ MEAN*100=SQRT(OMEGA)*100
(and it should be OMEGA, not eta in that expression that you mentioned)
Hope this helps,
Leonid
