Entering data in a Jolly-Seber summary table
|Top Previous Next|
This data table can be created from either individual or batch tagging information. If you have individual tagging information then this can be entered as full individual tagging data and the program will create this table for you. You can see an example of this type of data set by opening the example file Jolly-summary.csv.
Having selected Jolly Type Summary, you are asked to enter the number of sampling occasions undertaken.
Enter an integer number and click on OK.
You will then be presented with an empty data grid.
Column 1 gives the number of the sampling occasion, i, and is filled automatically after you have entered the number of sampling occasions.
Column 2 holds the number of time steps between samples. These values do not need to be entered if you are undertaking a standard Jolly-Seber analysis. They become necessary if the constant probability of capture and survival version of the Jolly-Seber model is used. If no values are entered then a time step of 1 is assumed.
Column 3 holds the total number of animals caught on occasion i.
Column 4 holds the number released with tags – this will not be the same as the number in column 2 if animals were killed in the trap or during handling.
The rest of the table comprises the lower half of a square matrix in which are entered the number of animals captured at time i which were last previously captured in samples 1 to i-1.
