Gibbs sampling algorithms were implemented to the multi-trait threshold animal models with any combinations of multiple binary, ordered categorical, and linear traits and investigate the amount of bia...
利用Bayesian-MCMC方法对不同家系结构的畜禽远交群体的二级离散性状进行QTL连锁检测，在分析中，基于IBD方差组分的随机模型的定位策略，同时利用MCMC的3种不同抽样技术（Gibbs抽样、Metropolis抽样和Reversible jump MCMC抽样）产生相应QTL参数的后验样本，在此基础上进行目标参数的Bayesian统计推断。结果表明： Bayesian-MCMC方法能够对Q...
