Linear Mixed-Effects Models Using R: A Step-by-Step Approach
by Andrzej Gałecki, Tomasz Burzykowski
⇥ Instead of using a simple function, e.g., a logarithm, to transform a covariate, a more flexible transformation can be used. For instance, the use of a spline can be considered. In general, a spline is a sufficiently smooth piecewise-polynomial function. It allows for modeling a complex nonlinear relationship between the dependent variable and a covariate.🏁
