The dimension of delivered placentae mirrors the cumulative conception to parturition. Placental weight is the gross summary of fetal growth under the influence of many extrinsic and intrinsic factors. Hence, the present study evaluated the influence of gestation, sex of the newborn, and parity on feto singleton newborn from a teaching hospital of North Karnataka, India. Data was collected from...

Likelihood ratio tests are intuitively appealing. Nevertheless, a number of examples are known in which they perform very poorly. The present paper discusses a large class of situations in which this is the case, and analyzes just how intuition misleads us; it also presents an alternative approach which in these situations is optimal. 1. The popularity of likelihood ratio tests Faced with a new...

The covariate shift is a challenging problem in supervised learning that results from the discrepancy between the training and test distributions. An effective approach which recently drew a considerable attention in the research community is to reweight the training samples to minimize that discrepancy. In specific, many methods are based on developing Density-ratio (DR) estimation techniques ...

In this work, we introduce an information-theoretic based correction term to the likelihood ratio classification method for multiple classes. Under certain conditions, the term is sufficient for optimally correcting the difference between the true and estimated likelihood ratio, and we analyze this in the Gaussian case. We find that the new correction term significantly improves the classificat...

INTRODUCTION.The RATIO DETECTOR uses a double-tuned transformer to convert the instantaneous frequency variations of the fm input signal to instantaneous amplitude.AM version is shown at A to make it a CWSSB receiver, change the detector to a. 4An FM ratio detector of the type mentioned in the text. It is similar to the.Ratio detector or discriminator was widely used for FM demodulation within ...

Reentrant polymer foam materials with negative Poisson's ratios, as described by Lakes (1), are a new class of materials with unique properties. The thermodynamic restriction on the compressibility, K, of an elastic material is that it must be positive for stability. The compressibility is related to the shear modulus, G, and Poisson's ratio, v, by K = 3/2[(1 2v)/G(1+ v)], so v is restricted to...

Results from the analysis of data collected at the Tevatron pp collider at center of mass energies p s = 630 and 1800 GeV collected by the DD and CDF experiments are presented. Measurements of the inclusive production jet cross section, the inclusive dijet mass spectrum, the triple diierential dijet cross section, and the dijet angular distribution are compared to order 3 s QCD predictions.

Previously, we have employed a program (Jtest) to test an hypothesis involving many parameters (multiple constraints). This test, which involves comparing parameter estimates with hypothesized values, is known as a Wald test. We also used the Jtest program to compare two di¤erent estimators in a Hausman test. There is an alternative method for conducting joint tests, which can be implemented ea...
