Table 2 Family distribution, link function, fixed effects and random effects specified in the model as a function of the kinematic parameter analyzed.

The family distribution refers to the distribution of the dependent variable. The link function consists in the mathematical function characterizing the relationship between the fixed factors and the dependent variable. The elements before and after (|) refer to the random slopes and random intercepts respectively. ^*Glmer function used with a Gaussian distribution and a link “identity” corresponds to a linear mixed-effect model.
