a
These estimates are not the probabilities. These are the outcome from the GLME. The probabilities are derived by plugging these values into the logistic function;
b
The intercept is considered at the 15th month of age;
c
These estimates are not the number of bouts or seconds. These are the outcome from the GLME. The real values are derived by plugging these values on the exponential function;
