A SUCCESSIVE DISCRIMINATION FORECAST OF MARINE WATER MASSES

Li Fengqi Su Yusong(Department of Physical Oceanography and Marine Meteorology)  
Discrimination analysis is one of the multivariate analysis methods. We apply it to the discrimination forecast of marine water masses. A method of successive discimination is utilized to select factors. The F-test is made with reference to .the Wilks value for each factor. The factor which has great "ability" of discrimination is selected successively. And a factor is immediately disqualified from discriminant when its "ability" declines because of the combination of given factors. A Fisher successive discriminant of forecast is given with reference to the information of matrix transformation. A multistage strength forecast of the Northern Huanghai Sea Cold Water Mass is taken as an example. The whole process of sifting factors and establishing discriminant is given. The effect of forecast is tested by historical data. A comparison is made between the above method and the conventionally used Bayes successive discrimination forecast.
