6-4-6 Performing Statistical Calculations k Estimated Value Calculation ( , ) After drawing a regression graph with the STAT mode, you can use the RUN • MAT mode to calculate estimated values for the regression graph's x and y parameters. Example To perform a linear regression using the nearby data and estimate the values of and when xi = 20 and yi = 1000 xi yi 10 1003 15 1005 20 1010 25 1011 30 1014 1. From the Main Menu, enter the STAT mode. 2. Input data into the list and draw the linear regression graph. 3. From the Main Menu, enter the RUN • MAT mode. 4. Press the keys as follows. ca(value of xi) K5(STAT)2( )w The estimated value is displayed for xi = 20. baaa(value of yi) 1( )w The estimated value is displayed for yi = 1000. # You cannot obtain estimated values for a MedMed, quadratic regression, cubic regression, quartic regression, sinusoidal regression, or logistic regression graph. 20050401
