Performing Statistical Calculations

kEstimated 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

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 valueis displayed for yi = 1000.

xi	yi
10	1003
15	1005
20	1010
25	1011
30	1014

# You cannot obtain estimated values for a Med-	quartic regression, sinusoidal regression, or
Med, quadratic regression, cubic regression,	logistic regression graph.
