WebbThe Standardised Major Axis Tests and Routines (SMATR) software provides tools for estimation and inference about allometric lines, currently widely used in ecology and evolution. 2. This paper describes some significant improvements to the functionality of the package, now available on R in smatr version 3. Webb18 mars 2024 · Second, we used standardized major axis (SMA) regressions to evaluate the trait correlations illustrated in Figure 1. The SMA was used because we wanted to generate a scaling relationship between traits, and the traits as both responses and predictors had measurement errors. The R 2 from SMA regression was same as the …
