• Why do we need to estimate the entire distribution? The distribution of an economic entity is of fundamental importance to decision makers, especially if they are risk averse and the underlying distribution is not Gaussian, a situation that calls for consideration of factors beyond the usual mean variance analysis. In particular the tail distribution plays a particularly crucial role in risk ...

We uncovered the universal statistical laws for the biomolecular recognition/binding process. We quantified the statistical energy landscapes for binding, from which we can characterize the distributions of the binding free energy (affinity), the equilibrium constants, the kinetics and the specificity by exploring the different ligands binding with a particular receptor. The results of the anal...

Measurements of second-stage juveniles of Heterodera schachtii from California and The Netherlands and a race of H. trifolii from The Netherlands were obtained and compared to determine if these populations can be differentiated by morphometrics. Juvenile lengths of 10 specimens from each of 10 cysts of each population were measured. Dimensions of tail regions of 20 juveniles from individual cy...

Abstract Value-at-risk is one of the most popular risk management tools in financial industry. Over past 20 years, several attempts to include VaR portfolio selection process have been proposed. However, using as a measure optimization models leads problems that are computationally hard solve. In view this, few practical applications appeared literature up now. this paper, we propose add criter...

One goal in simulation experimentation is to identify which input parameters most significantly influence the mean of simulation output. Another goal is to obtain good parameter estimates for a response model that quantifies how the mean output depends on influential input parameters. The majority of experimental design techniques focus on either one goal or the other. This paper uses a design ...

the objective followed in the present study was to survey the relationship between 18 body trait measurements (live weight, height at wither, paunch girth, neck diameter, body length, girth around the body, width of fat tail at above, below and midpoint of fat tail, fat tail length lowers right and left sides, fat tail gap length, fat tail depth at the above, below, and midpoint, and girth arou...

For a large class of distributions and large samples, it is shown that estimates of the variance σ2 and of the standard deviation σ are more often Pitman closer to their target than the corresponding shrinkage estimates which improve the mean squared error. Our results indicate that Pitman closeness criterion, despite its controversial nature, should be regarded as a useful and complementary to...

Market-makers have the obligation to trade fixed amounts of assets at quoted bid or ask prices, and their inventories are exposed to the potential loss when the market price moves in an undesirable direction. One approach to reduce the risk associated with price uncertainty is to adjust the inventory at the price of losing potential spread gain. For a single-asset model, we show that a threshol...
