Linear Regression Models with Logarithmic Transformations

kenbenoit.net

Logarithmic transformations are also a convenient means of transforming a highly skewed variable into one that is more approximately normal. (In fact, there is a distribution called the log-normal distribution deﬁned as a distribution whose logarithm is normally distributed – but whose untrans-formed scale is skewed.)

and logarithmic transformations. Further to this, trends can also be removed (e.g., by subtracting the overall mean of a time series), smoothing can be done by replacing the time series with a moving average, and other transformations may be useful as well (e.g., standardization or Box-Cox). In general, it is also good practice to clean

Linear regression: before and after ﬁtting the model It is not always appropriate to ﬁt a classical linear regression model using data in their raw form. As we discuss in Sections 4.1 and 4.4, linear and logarithmic transformations can sometimes help in the interpretation of the model. Nonlinear
