Abstract:Constellation diagram and contiguous vector diagram are audiovisual methods in multivariate statistics,they may be used for the cluster analysis of multivariate sample or index.This paper implements their automatic drawing programs in microcomputer.So long as the sample data are inputted,the computer may carry out their correlation analysis between variables,the standardization of data,and draw their constellation diagram and contiguous vector diagram,which are clear and convenient for the user.This method is suitable for the condition that the sample size and the number of variables are small.
Keywords:multivariate analysis  constellation diagram  contiguous vector diagram  microcomputer
