Regression Coefficient and Estimated Value Commands for Non- quadratic Regression (VAR Menu)

The calculation that is performed when one of these commands is performed depends on the regression type that is currently selected. For details about each regression calculation formula, see “Regression Coefficient and Estimated Value Calculation Formula Table” (page 47).

a12(S-VAR)1(VAR)ee1

Obtains constant term a of the regression formula.

b12(S-VAR)1(VAR)ee2

Obtains coefficient b of the regression formula.

r12(S-VAR)1(VAR)ee3

Obtains correlation coefficient r.

xˆ

12(S-VAR)1(VAR)d1

Taking the value input immediately before this command as the y-value, obtains the estimated value of x based on the regression formula for the currently selected regression calculation.

yˆ

12(S-VAR)1(VAR)d2

Taking the value input immediately before this command as the x-value, obtains the estimated value of y based on the regression formula for the currently selected regression calculation.
