In order to cover all comorbidities which may not be contained in the aDCSI, we additionally calculated the Charlson Comorbidity index (CCI; Additional file 2: Table S2) [ 23].
To investigate the influence of each single song variable of the reduced data set in more detail, we additionally calculated Spearman correlations between song variables and male feeding rate (see also Additional file 1 for detailed results).
We additionally calculated the average correlation coefficient for longer time windows of interest.
Checking possible nesting-effects of class-affiliation, we additionally calculated the null model with repeated measures nested within classes.
The resistance (Ri) for these SDs was additionally calculated from Ohm's law as function of voltage for each diode.
We additionally calculated V T values by a one-compartment model and obtained estimates similar to the graphical plot results (Table 4).
This finding was independent from the used data source, that is, associations reported in the literature and correlation coefficients additionally calculated from extracted pre and post practice data for measures of motor performance and myoelectric activity.
Because the estimated coefficients of the Tobit-Model refer to the latent variable, marginal effects are additionally calculated, which represent the effects of the explanatory variables on the expected value of the dependent variable evaluated at the mean values of the explanatory variables.
