this article examines statistical inference for  where and are independent but not identically distributed pareto of the first kind (pareto (i)) random variables with same scale parameter but different shape parameters. the maximum likelihood, uniformly minimum variance unbiased and bayes estimators with gamma prior are used for this purpose. simulation studies which compare the estimators are ...

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...

The primary structure of Cerebratulus lacteus toxin B-II has been investigated by automated Edman degradation of the reduced, carboxymethylated protein and of tryptic peptides derived from the maleylated protein. As a result of these studies, the identity of all 55 amino acid residues in the polypeptide chain has been unambiguously determined. Hydroxyproline, an amino acid not normally found in...
