Transformations for Linearity and Constant Variance
A scatterplot of two variables reveals a curved relationship. The corresponding residual plot has a U-shape, and the variability of the response variable increases as the explanatory variable increases. Which of the following transformations would most effectively linearize the data and stabilize the variance?
A
Log(y) and log(x)
B
Log(y) only
C
Square root of y and x²
D
1/y and log(x)
