Regression Coefficient and Estimated Value Commands

The values obtained by the following commands depend on the regression formula used for the calculation. The regression formula used is the one that is applicable for the regression calculation result screen (page 78) that was last displayed in the REG Mode.

a

z7(STAT)2(VAR)ccc1
Obtains coefficient a of the regression formula.

 

 

 

b

z7(STAT)2(VAR)ccc2
Obtains coefficient b of the regression formula.

 

 

 

c

z7(STAT)2(VAR)ccc3
This command is supported for quadratic regression only.

It obtains coefficient c of the regression formula.

 

 

 

r

z7(STAT)2(VAR)ccc4

 

 

Obtains correlation coefficient r.This command is not supported for quadratic regression.1z7(STAT)2(VAR)ccc5

Obtains the estimated value of x for a value of y, which is assumed to be the value input immediately before this command.

2

z7(STAT)2(VAR)ccc6

This command is supported for quadratic regression only.

It obtains the second estimated value of x for a value of y, which is assumed to be the value input immediately before this command. When used in a calculation that is not a quadratic regression calculation, this command produces the same results as the m1 command.

z7(STAT)2(VAR)ccc7

Obtains the estimated value of y for a value of x, which is assumed to be the value input immediately before this command.

ARegression Coefficient and Estimated Value Calculations

The formulas used by the regression coefficient and estimated value commands depend on the regression calculation type. For details about regression calculation formulas, see <#02> and <#08> in the separate Supplement.
