Entering data in a closed summary table
|Top Previous Next|
This data table can be created from either individual tagging data 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 Closed_summary.csv.
Having selected Closed Type Summary, you are asked to enter the number of sampling occasions undertaken.
Four data vectors each placed on a separate row are required.
Row 1 gives the sample number and is filled in automatically when you have specified the number of samples taken.
Row 2 holds the number of animals caught on each sampling occasion, N(i).
Row 3 holds the number of marked animals in the population, M(i). For sample i, this is the sum of the newly caught animals from sample 1 to sample i-1. If any animals were killed during capture and handling they must also be subtracted.
Row 4 holds the number of animals newly captured in the ith sample, U(i). These are the captured individuals that bear no previous mark.
Row 5 is the frequency distribution of the times of capture. Enter here a count of the number of individuals caught 1, 2, or more times during the study, F(i).
The figure below shows a typical example. Click within the boxes of dashed lines for an explanation of the rows.
