PROBLEM TO BE SOLVED: To confirm a regression equation which is designated again with simple operation, after calculation of regression.SOLUTION: A scientific calculator 1 has a CPU 15 which performs regression calculation about a regression equation which is subjected to user designation, about a set of numeric data formed of an independent variable and dependent variable, and calculates a coefficient value of the regression equation. When the coefficient value of the regression equation is calculated, and then a user performs coefficient value calculation start operation, the CPU 15 displays the regression equation on a display part 12, and calculates the displayed regression equation by the calculated coefficient value. |
