Table 2. Results of analyses of different response variables as a function of fish size.

Columns in order: response variables, p-value of the Phi coefficient, p-value of the RM test to residuals, evaluation of the presence of a significant covariance (True or False), pseudo R² (with link transformation of response variable), mean estimate of analysis, Std. Error of analysis, and the Z-value and P-value of the beta regression analysis.
