Analysis of participants data

On Friday (possibly also on Tuesday and Wednesday evenings) we will work on participants’ data. Please prepare your data in the following way:

Capture history format:
The preferred format is the capture or encounter history. In a mark-recapture encounter history with a single site, the history consists of a contiguous series of "1"s and "0"s, where "1" indicates that the animal was marked or recaptured (resighted), and "0" indicates that the animal was not captured. If you have several states (e.g. geographical sites), use 1, 2, 3 etc for the successive states in place of 1’s.
Example for 8 occasions : 30102002
(initial capture at occasion 1 on site 3, then recaptures at occasion 3 on site 1 and at occasions 5 and 8 on site 2)
Each history is followed by one or more additional columns of information and ends with a semicolon.

  • 1 column : a number in one additional column indicates the frequency of individuals having a particular encounter history (this number can be 1)

Example 1 : (one line for each individual)
10000000 1;
10000000 1;
11100000 1;
11000000 1;
11010000 1;

Example 2 : (The summary of example 1, grouped by encounter history)
10000000 2;
11100000 1;
11000000 1;
11010000 1;

  • Multiple columns : if you have multiple groups, add one column of frequency per additional group

Example 3 : Male and female summary encounter histories:
10000000 60 89;
11000000 42 31;
11001000 2 9;

Save the file in an ASCII (text) format.

variables:

individual covariates should be entered as supplementary final column(s) in the encounter history file (then, only individuals with the same capture history and the same values of covariates may be grouped).

If you have covariates other than individual covariates such as meteorological data organize them in a separate ASCII text file with the following structure:

line1: number of covariates
line2: list of the size of each covariate
line3: list of the values of the first covariate
line4: list of the values of the second covariate
...

Example: 2 covariates of respective length 8 and 5

2
8 5
0.2 0.33 -0.5 0.0 1.0 -0.8 -0.1 0.25
1 1 0 2 3
