1. Ecological count data (e.g., number of individuals or species) are often log-transformed to satisfy parametric test assumptions.2. Apart from the fact that generalized linear models are better ...

The log transformation is often used to convert time series that are nonstationary with respect to the innovation variance into stationary time series. The usual approach is to take the log of the ...

The most common transformations are available in the Edit:Variables menu. For example, log transformations are commonly used to linearize relationships, stabilize variances, or reduce skewness.
