Local Kernel Dimension Reduction in Approximate Bayesian Computation
《Open Journal of Statistics》2018年第3期479-496,共18页Jin Zhou Kenji Fukumizu 
Approximate Bayesian Computation (ABC) is a popular sampling method in applications involving intractable likelihood functions. Instead of evaluating the likelihood function, ABC approximates the posterior distributio...

利用近似贝氏计算推论台湾海峡沿岸秋茄种群的拓殖路线被引量：6
《生态学报》2015年第13期4304-4313,共10页阮宇 吕佳 李俊清 肖国生 
由ITTO(国际木材组织)与国家林业局共同资助《通过社区发展和能力建设实现中国红树林可持续经营(PD 460/07 Rev.2(F》
由于地理关系,台湾海峡两岸的红树植物组成具有高度的相似性,都以耐寒性较强的秋茄为优势种。中国台湾(以下简称"台湾")与大陆仅一水之隔,因此台湾的秋茄种群来源最有可能来自东南沿海种群,然而台湾南、北红树植物种群的拓殖路线以及与...
