| Abstract: | The principle component analysis, factor analysis and correspondence
analysis used in numerical taxonomy are compared both theoretically and practically. The advantage and disadvantage of all the methods and the problems existing in practice
were discussed.Then, the results of the numerical taxonomy were dealt with practically. |
