Abstract In every engineering application where the in epen ent variable an its intervals have to be estimate by the ran om
variable ( epen ent variable) ,we can. t ma e irect use of the regression analysis which has been evelope for estimating the ran om
variable an its intervals by in epen ent variables.Therefore a new inverse regression analysis is presente in this paper.This metho can
estimate the in epen ent variable an its intervals, an analyze its error. Meanwhile, a new metho of ata fusion is also establishe . In
the engineering measurement, the inverse regression analysis can correct its systematic error, an the ata fusion metho can re uce its
acci ental error.They have been use in the non estructive inspection of pressure containers an aircrafts successfully. It shows that the
measurement precisions have been raise greatly.
Key words Regression analysis; In erse regression analysis; Data fusion; Measurement; Calibration
