Logarithmic, Exponential, Power, and Inverse Regression Formulas

• Logarithmic Regression : y = A + Blnx
- Exponential Regression : y = ^Bx (Aey = InA + Bx)
• Power Regression : y = Ax^B(Iny = InA + BInx)
- Inverse Regression : y = A+Bx ^1

Quadratic Regression

• The quadratic regression is in relation to the formula:

$$ y = A + B x + C x ^ {2} $$

• Example: ABC company investigated the effectiveness of the advertisement expenses in coded units, the following data were obtained:

Advertisement expenses: x	18	35	40	21	19
Effectiveness: y (%)	38	54	59	40	38

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_1 , x_2 ) for the effectiveness y=50
