We present two algorithms for inducing structural equation models from data. Assuming no latent variables, these models have a causal interpretation and their parameters may be estimated by linear multiple regression. Our algorithms are comparable with PC [15] and IC [12, 11], which rely on conditional independence. We present the algorithms and empirical comparisons with PC and IC. This resear...

introduction: erythrocyte sedimentation rate (esr) remains as one of the most reliable tests in clinical practices. yet its use is time consuming and requires a large blood sample. the aim of this study was assessing a faster and reliable method of esr estimation. methods: an esr estimation method was described and performed on 108 patients using capillary tube (micro esr) and capillary periphe...

data on body weight and body measurements (body length, height at withers, chest girth and paunch girth) of adult kilakarsal sheep have been collected from 124 adult animals managed at the farmers filed in tirunelveli districts of tami nadu, india to estimate the body weight from body measurements. the data were subjected to standard statistical analysis using spss software and linear regressio...

drafts of major primary tillage implements were measured in a clay loam soil using a tension loadcell. implements consisted of a moldboard, a disk and a chisel plow each equipped with one tillage unit. a photoelectric speed sensor was used for actual forward speed measurements. during the study, the effects of forward speed and tillage depth on draft requirements were investigated. a general re...

A scheme for the generalized Chaplygin gas equation of state is shown by using holographic Ricci dark energy. Regression analysis and a chi-square test were performed. second order polynomial regression has been established as relation between Hubble Parameter redshift. It set parameters that can predict Equation State (EoS) parameter.

BACKGROUND Black individuals are far more likely than white individuals to develop end stage renal disease (ESRD). However, earlier stages of chronic kidney disease (CKD) have been reported to be less prevalent among blacks. This disparity remains poorly understood. The objective of this study was to evaluate whether the lower prevalence of CKD among blacks in early stages of CKD might be due i...

In this paper, we applied the support vector machine (SVM) to the spatial interpolation of the multi-year average annual precipitation in the Three Gorges Region basin. By combining it with the inverse distance weighting and ordinary kriging method, we constructed the SVM residual inverse distance weighting, as well as the SVM residual kriging precipitation interpolation model and compared them...

  Crop yields are dependent on a number of factors such as soil type, weather conditions and farming practices. Crop yield estimates in different soil types are required to meet the needs of farmers, land appraisers, and governmental agencies in Iran as around the world. This study was conducted to model the wheat-grain yields [Triticum aestivum L.]  by soil properties in Khoy area, the north-w...

The recent credit crisis has heightened the awareness of credit risk among financial markets’ regulators and participants. However, despite the public discussion on centralized processing systems for the off-exchange traded (Over-The-Counter, OTC) transactions no research has been conducted on the factors that could explain their adoption among market participants. With this study, an attempt i...

In the remainder, we call such a variety a convex symplectic variety. A convex symplectic variety has been studied in [K-V], [Ka 1] and [G-K]. One of main difficulties we meet is the fact that tangent objects TX and T 1 Y are not finite dimensional, since Y may possibly have non-isolated singularities; hence the usual deformation theory does not work well. Instead, in [K-V], [G-K], they introdu...
