Parametric and nonparametric methods have been developed for purposes of predicting phenotypes. These methods are based on retrospective analyses of empirical data consisting of genotypic and phenotypic scores. Recent reports have indicated that parametric methods are unable to predict phenotypes of traits with known epistatic genetic architectures. Herein, we review parametric methods includin...
Consider the problem of comparing parametric models M 1 ; : : : ; M k , when at least one of the models has an improper prior N i (i). Using the Bayes factor for comparing among these is not feasible due to arbitrary multiplicative constants in N (i). In this work we suggest adjusting the initial priors for each model, N i , by i (i) = Z N i (i jy)m (y)dy where m is a suitable predictive measur...
This research work primarily focuses on enhancing the power conversion efficiency (PCE) of polycrystalline silicon solar cells by using a single-layer and double-layered antireflection coating deposited through electrospraying technique. The usage titanium dioxide as materials has shown significant increase in optical electrical properties under open controlled light sources. sample with TiO2 b...
In this study, the application of Bayes networks and fault tree analysis in reliability estimation have been investigated. Fault tree analysis is one of the most widely used methods for estimating reliability. In recent years, a method called "Bayes Network" has been used, which is a dynamic method, and information about the probable failure of the system components will be updated according to...
Total number of abortions: 30,699. 60% of abortions were criminal and the re- mainder were due to: (a)Cervical incompetence (b) hypothyr oidism (c) Listeriosis (d) Toxoplasmosis (e) Luteal phase deficiency (f) Placental deficiency Mg) Rh and ABO incompatibility and unknown etiology. Therapeutic abortions were also performed in several cases due to: (a) Miliary tube...
We develop a new semiparametric Bayes instrumental variables estimation method. employ the form of regression function reduced-form equation and disturbances are modelled nonparametrically to achieve better preditive power endogenous variables, whereas we use parametric formulation in structural equation, which is interest inference. Our simulation studies show that under small sample size prop...
The author evaluated the implications of nominal statistical significance for changing the credibility of null versus alternative hypotheses across a large number of observational associations for which formal statistical significance (p < 0.05) was claimed. Calculation of the Bayes factor (B) under different assumptions was performed on 272 observational associations published in 2004-2005 and...
