Size 58 KB DescriptionWinBUGS code was run on version 1.4 available at http://www.mrc-bsu.cam.ac.uk/bugs/winbugs/contents.shtml. We use the following generic script: display('log') check('directory/model_name.txt') data('directory/data_file.txt') compile(4) inits(1, 'directory/filename1_ini.txt') inits(2, 'switch/filename2_ini.txt') inits(3, 'switch/filename3_ini.txt') inits(4, 'switch/filename4_ini.txt') gen.inits() set(parameter_names) over.relax('yes') update(50000) stats(*) quantiles(*) coda(*,switch/output) See the WinBUGS manual for details on how to run the analysis. Matlab code was run on student version 6.5.文件清单 singlet.txt：用于“单随机游走（Single Random Walk）”模型的WinBUGS代码，大小2 KB。 double.txt：用于“双随机游走（Double Random Walk）”模型的WinBUGS代码，大小2 KB。 double_covar.txt：用于“带协变量双随机游走（Double with Covariates）”模型的WinBUGS代码，大小3 KB。 double_switch.txt：用于“双切换（Double Switch）”模型的WinBUGS代码，大小3 KB。 switch_covar.txt：用于“带协变量切换（Switch with Covariates）”模型的WinBUGS代码，大小3 KB。 switch_constrained.txt：用于“约束切换（Switch Constrained）”模型的WinBUGS代码，大小3 KB。 triple_switch.txt：用于“三切换（Triple Switch）”模型的WinBUGS代码，大小2 KB。 HierSwitch.txt：用于切换模型分层版本的WinBUGS代码，大小3 KB。 simulasw.m：用于运动模拟的Matlab代码，大小5 KB。 PPcheck.m：用于后验预测检查（posterior predictive check）的Matlab代码，大小7 KB。 elk_data.txt：4头麋鹿的运动数据集，大小87 KB。 simulated.txt：通过simulasw.m生成的模拟运动数据集，大小46 KB。 allfiles.zip：全部文件打包压缩包，大小58 KB。 描述：本数据集的WinBUGS代码运行于版本1.4，该版本可从http://www.mrc-bsu.cam.ac.uk/bugs/winbugs/contents.shtml获取。我们采用如下通用分析脚本： display('log') check('directory/model_name.txt') data('directory/data_file.txt') compile(4) inits(1, 'directory/filename1_ini.txt') inits(2, 'switch/filename2_ini.txt') inits(3, 'switch/filename3_ini.txt') inits(4, 'switch/filename4_ini.txt') gen.inits() set(parameter_names) over.relax('yes') update(50000) stats(*) quantiles(*) coda(*,switch/output) 有关该分析的详细运行步骤，请参阅WinBUGS官方手册。本数据集附带的Matlab代码运行于6.5学生版。
