| Abstract: | In this paper, some problems of temary code of quantitative data are discussed in detail. It is suggested that the binary code data should be used in stead of temary data in characteristic analysis. On the basis of this study, some improvements in the characteristic model are studied. We thind that there may be some weight for the absence of the variables. At last, the application of the improved model for quantitative prediction of the gold deposit is given. |

| Keywords: | characteristic analysis binary variable variable weight ore-forming favorability |
