In this article the fitting degree of regression straight line and real measuring points are discussed in fuzzy mathematical method It is put forward that fitting degree of regression straight line A computational method of fitting degree of regression straight line is give

76%;fitting degree of weighted seismic record and well side seismic channel is 0,509,far higher than that of Gardner and Faust formulae synthesized seismic record.

On the base of brief introduction of the basic theory of multiple regression,this article gives the multiple estimation regression equation applied to predict the apoplexy risk and tests the equation s validity by the test of regression model′s hypothesizes、significance of regression relationship and the goodness of fit.
