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.
