Top  Previous  Next

This tab presents the Gulland plot of your length data. It shows the incremental increase in length at each length. It is only shown if you run a von Bertalanffy growth model. This plot can be useful to help you estimate initial parameters for nonlinear regression. It is also useful to assess the goodness of fit of the chosen model, as the predicted line for the chosen model is marked on the plot.

 

The graph below shows a typical example using the bass.csv data. The green line is the model prediction.
