calculate the elasticities by linear.hypothesi commander
...ist(formulas1,formulas2) > > salmon1=systemfit(formulas12, data=Fsalmon2, method="SUR") > summary (salmon1) >MWfresh<-mean (Wfresh2, data=Fsalmon) >MWfrozen<-mean (Wfrozen2, data=Fsalmon) >MWsmoke<-mean (Wsmoke2, data=Fsalmon) >restricte11=c("eq1_dlnPfresh/MWfresh-1=0") >linear.hypothesis(salmonsdlnf1r, restricte11, test="Chisq") It does not work. However, if I replace MWfresh with the pure numerical number restricte11=c("eq1_dlnPfresh/0.42-1=0") It works. Can anyone help me to work it out.? Thanks...
