Supplement 1. Source code and example data for fitting the kittiwake data set by maximum likelihood.

File List likelihood_and_data.m (MD5: 34a30beedca4926806b03ae1e1527fe2) Description The likelihood_and_data.m is matlab code developed to fit the kittiwake data set by maximum likelihood (f1_individuelle) as implemented in Matlab 8 R2012b. The kittiwake capture–recapture data set is provided and imputed by the function kittiwake. The function likelihood_and_data reads the data, computes the maximum likelihood estimator for survival (s), transitions (tr_NN, tr_PP) and means (m_N, m_P) and variances (var_N, var_P) of the two normal distributions.

文件列表 likelihood_and_data.m（MD5值：34a30beedca4926806b03ae1e1527fe2） 说明：likelihood_and_data.m 为基于MATLAB 8 R2012b实现的MATLAB代码，用于通过极大似然法拟合三趾鸥（kittiwake）数据集，该极大似然法对应函数f1_individuelle。三趾鸥捕获-再捕获数据集由kittiwake函数提供并完成缺失值插补。该likelihood_and_data函数可读取数据集，并计算两个正态分布的生存参数（s）、转移参数（tr_NN、tr_PP）、均值参数（m_N、m_P）以及方差参数（var_N、var_P）的极大似然估计值。
