Importance Sampling
We describe an application of using a change of sampling density to get easier access to rare events during numeric simulations (this is called importance sampling). Our emphasis is on the derivation of the change of density instead of the algorithmic details. We work a small example to make the technique concrete.
متن کاملUniparental (mtDNA, Y-chromosome) polymorphisms in French Guiana and two related populations--implications for the region's colonization.
Blood samples collected in four Amerindian French Guiana populations (Palikur, Emerillon, Wayampi and Kali'na) in the early 1980s were screened for selected mtDNA and Y-chromosome length polymorphisms, and sequenced for the mtDNA hypervariable segment I (HVS-I). In addition, two other Amerindian populations (Apalaí and Matsiguenga) were examined for the same markers to establish the genetic rel...
متن کاملPolymorphisms in GDF9 Gene and Its Relationship with Litter Size in Five Breeds of Black Goats
In this study, we investigated the relationship between the genetic polymorphism of growth differentiation factor 9 (GDF9) genes and the litter size in 384 individuals of five breeds of black goats. Four pairs of primers were designed to detect single nucleotide polymorphism of GDF9 gene in goats by PCR-SSCP. The least square was used to analyze the relation between different genotypes and the ...
متن کاملRegional Variation in Mtdna of the Lesser Prairie-chicken
reprintInfo.asp. DOI: 10.1525/cond.2010.090150 Resumen. La pérdida de hábitat y la disminución poblacional de largo plazo sufrida por Tympanuchus pallidicinctus ha conducido a preocupaciones en torno a la viabilidad de la especie a lo largo de su distribución geográfica en la parte sur de las Grandes Planicies. Para que la conservación sea más eficiente, es necesario entender la distribución pa...
متن کاملAdvances in Lifted Importance Sampling
We consider lifted importance sampling (LIS), a previously proposed approximate inference algorithm for statistical relational learning (SRL) models. LIS achieves substantial variance reduction over conventional importance sampling by using various lifting rules that take advantage of the symmetry in the relational representation. However, it suffers from two drawbacks. First, it does not take ...
