Calculate linear regression equation2/19/2024 Precautions when editing data input for standard deviation also apply for regression calculations.ĭo not use variables A through F, X, or Y to store data when performing statistical calculations. The above results can be obtained in any order, and not necessarily that shown above. To input the data "20 and 30" five times, for example, press 20 30 ( ) 5. You can also input multiple entries of the same data using ( ). Next, use the regression formula to estimate the values for y ˆ (estimated value of y) for x i = 16 and x ˆ (estimated value of x) for y i = 20. The following shows the regression formulas for each type of regression. Use the same key operations as linear regression to recall results for these types of regression. Logarithmic, Exponential, Power, and Inverse Regression Finally, calculate the coefficient of determination (r 2) and sample covariance ( ∑ xy - n∙ x -∙ y - n - 1).Įach time you press to register your input, the number of data input up to that point is indicated on the display ( n value).Ĭoefficient of Determination = 0.965517241 Next, use the regression formula to estimate atmospheric pressure at -5☌ and temperature at 1000 hPa. Function Calculation Input Ranges and Precision.▶Calculation Ranges, Number of Digits, and Precision.
