The popular concept of object is introduced, and the operation is flexible and simple. Various operation modes can be used for quantitative analysis and statistical analysis, and data management is simple and convenient. Its main functions are:

(1) Manage data in a unified way, and realize various operations on data through objects, views and processes;

(2) Input, expand and modify time series data or segmented data, and generate new series according to any complicated formula and existing series;

(3) Calculate descriptive statistics: correlation coefficient, covariance, autocorrelation coefficient, cross correlation coefficient and histogram;

(4) t

Test, analysis of variance, cointegration test, Granger
