Data: This tab shows age and size data. For example, it will be displayed if you have entered or opened a data set that comprises age and length data for individual organisms.

Calculations: This tab presents the observed and predicted values.

Graph + Results: This tab presented a plot of the observed and predicted fit plus model parameters and diagnostics for length data.

 

To get you started Removal Sampling 2 comes with a demo data set.

 

Use File|Open to find and open RemovalDemo.csv (saved by default during installation in the folder ..\My Documents\Removal Sampling Data\Demo Data)

 

This will give a plot of your data in a tabbed output. Upon opening the data set Removal Sampling 2 automatically fits a constant probability model using non-linear methods. If you wish to fit another model, this is easily accomplished - choose another from the Method drop-down menu:
