The data analysis and smart discriminant method based on fisher model

Fisher discriminant model was used to find the rule between discriminant factors and water quality types, and the discriminant function model of water inrush source was established, which was tested by water samples to be judged. On the basis of previous studies, the discriminant method model selects 6 kinds of conventional hydrochemical ions, pH and total dissolved solids, and a total of 8 kinds of hydrochemical factors to analyze.
