Regression

Use the [MODE] key to enter the Regression (REG) mode when you want to perform statistical calculations using regression. [MODE] [3]

When you enter Regression mode, you can select from 6 types of regression:

Linear regression	[1]	(Lin)
Logarithmic regression	[2]	(Log)
Exponential regression	[3]	(Exp)
Power regression	→ [1]		(Pwr)
Inverse regression	→ [2]		(Inv)
Quadratic regression	→ [3]		(Quad)

•To clear statistical memory, press [SHIFT] [CLR] [1] [=].

•To enter data, use the following key sequence: <x data> , <y data> [DT]

•The values produced by a regression calculation depend on the values input. Results can be recalled using the following:

∑ x2	[SHIFT] [S-SUM] [1]
∑ x	[SHIFT] [S-SUM] [2]
n	[SHIFT] [S-SUM] [3]
∑ y2	[SHIFT] [S-SUM] → [1]
∑ y	[SHIFT] [S-SUM] → [2]
∑ xy	[SHIFT] [S-SUM] → [3]
Mean of the x data	[SHIFT] [S-VAR] [1]
Population standard deviation (x)	[SHIFT] [S-VAR] [2]
Sample standard deviation (x)	[SHIFT] [S-VAR] [3]
Mean of the y data	[SHIFT] [S-VAR] → [1]
Population standard deviation (y)	[SHIFT] [S-VAR] → [2]
Sample standard deviation (y)	[SHIFT] [S-VAR] → [3]
Regression coefficient A	[SHIFT] [S-VAR] → → [1]
Regression coefficient B	[SHIFT] [S-VAR] → → [2]

For regression calculations other than quadratic regression:

Correlation coefficient r	[SHIFT] [S-VAR] → → [3]
Estimate x	[SHIFT] [S-VAR] → → → [1]
Estimate y	[SHIFT] [S-VAR] → → → [2]
For quadratic regression:
∑ x3	[SHIFT] [S-SUM] → → [1]
∑ x2 y	[SHIFT] [S-SUM] → → [2]
∑ x4	[SHIFT] [S-SUM] → → [3]
Regression coefficient C	[SHIFT] [S-VAR] → → [3]
Estimate x1	[SHIFT] [S-VAR] → → → [1]
Estimate x2	[SHIFT] [S-VAR] → → → [2]
Estimate y	[SHIFT] [S-VAR] → → → [3]
