PURPOSE:To perform processes under the same conditions by holding the final parameter supplied in terms of trial and error at a memory and displaying said parameter in a reprocessing mode. CONSTITUTION:When the sale is estimated by a regression analysis method, a statistic subsystem processing part 8 reads out commands, conditions, etc. out of a command condition holding part 5 with an indication of a keyboard. Then the part 8 calculates an estimated sales amount by a regression analysis method and displays it at a display part 2. In this case, a system control part 1 copies each data to a simulation area 7-0 of a memory 7. When it is decided from the result of estimation that the conclusion is not desirable in response to the past data, etc., a retrial key on the keyboard is pushed. Thus the retrial is repeated until the estimated arithmetic result is coincident with the desired value. In the same way, the estimation processing is carried out to other data after the satisfactory result of estimation is obtained together with the result of display. In such a case, the reprocessing items of an initial menu are selected through the keyboard and processed again in the same procedure by different analysis data. |
