PURPOSE:To easily and objectively perform the analysis of data series and the prediction of future data when a data series is converted to a graph. CONSTITUTION:When the data series is inputted to a work sheet 3 and it is graphically displayed in continuous line on a graphic screen 4, the approximate expression of a graph in continuous line is found by a method of least square, etc., by command input, and it is displayed on a numerical bar 2, and also, the graph of the approximate expression is displayed in dotted line on the graphic screen 4, and also, numerical data by the approximate expression is described on the work sheet 3. The approximate expression can be automatically found by the command input, and the analysis and the prediction of the data are performed by using the approximate expression, therefore, the analysis and the objective prediction of the data can be performed with a simple operation such as the command input. |
