Regression calibration has been described as a means of correcting effects of measurement error for normally distributed dietary variables. When foods are the items of interest, true distributions of intake are often positively skewed, may contain many zeroes, and are usually not described by well-known statistical distributions. The authors considered the validity of regression calibration ass...

We consider a Bayesian analysis of Binomial response data with covariates. To describe the problem under investigation, suppose we have n independent binomial observations Y1, . . . , Yn where Yi ∼ Bin(mi, θi) and let xi be p-dimensional covariate vector associated with Yi for i = 1, . . . , n. Binomial observations can be analyzed through a generalized linear model (GLM) where we assume θi = F...

Thirty-one females with incontinentia pigmenti (IP), 42 controls, and 11 females from four families segregating for X linked lymphoproliferative disease (XLP) were studied for evidence of skewed X inactivation by analysis of methylation at sites in the HPRT, PGK, and M27 beta (DXS255) regions of the X chromosome. Extensive skewing of X inactivation was present in blood from 4/42 (9.5%) control ...

As with the advancement of geographical information systems, non-Gaussian spatial data sets are getting larger and more diverse. This study develops a general framework for fast flexible regression, especially spatial/spatiotemporal modeling. The developed model, termed compositionally-warped additive mixed model (CAMM), combines an (AMM) Gaussian process to wide variety continuous including ot...

Given the urgency of rising sea levels and need to sustain food production, developing flood-tolerant crops is essential. The aim this study was assess genetic potential cross CO51x13-6 (NIL CO43Sub1) in BC2F4 BC2F5 generations using Parent Offspring regression analysis. Significant variation observed across a wide range traits both generations. distribution important traits, including plant he...

BACKGROUND A higher frequency of skewed X chromosome inactivation has been reported in a consecutive series of young patients with breast cancer compared with controls of a similar age. OBJECTIVE To investigate the X inactivation pattern in patients with familial non-BRCA1/BRCA2 breast cancer (n = 272), BRCA1/BRCA2 germline mutations (n = 35), and sporadic breast cancer (n = 292). METHODS X...

Information technology and the media have changed the face of business practices today. Customers now play the key role for the success of any business and noncompliance to their specifications will simply lead to failure of the business. Researchers across many disciplines have worked out several modifications of the traditional process capability measures to obtain better estimates of the pro...

Normal state-space models are prevalent, but to increase the applicability of the Kalman filter, we propose mixtures of skewed, and extended skewed, Kalman filters. To do so, the closed skew-normal distribution is extended to a scalemixture class of closed skew-normal distributions. Some basic properties are derived and a class of closed skew-t distributions is obtained. Our suggested family of...

In this short note, we extend the notion of texture symmetry to the skewed symmetry and propose a method for calculating the skewed symmetry of a non-rectangular or affine-distorted bidirectional texture. Results for a number of natural textures are shown.

Recurrent spontaneous abortion (RSA) defines as two or more consecutive losses at < or = 20 weeks of gestation and affects an estimated 1 of every 100 couples wishing to have children. However, it remains a poorly understood phenomenon. Recent reports observed a significant association between highly skewed X chromosome and RSA, supporting that X chromosome inactivation might be an important an...
