Logarithmic, Exponential, Power, and Inverse Regression Formulas

Logarithmic Regression : y = A + Blnx
Exponential

Regression : y

(lny = lnA + Bx)

Power

Regression

: y

(lny = lnA + Blnx)

Inverse

Regression

: y

A+Bx

-1

Quadratic Regression

The quadratic regression is in relation to the formula:
y = A + Bx + Cx

Example:

ABC company investigated the effectiveness of the

advertisement expenses in coded units, the following data were
obtained:

Please calculate the correlation coefficient; use the regression to
estimate the effectiveness (estimate the value of y) if the
advertisement expenses x = 30, and estimate the advertisement
expenses level (estimate the value of x

, x

) for the effectiveness y=50
