BACKGROUND Fibroblast growth factor-23 (FGF-23), a novel marker of bone disease in chronic kidney disease (CKD) has been shown to correlate with vascular calcifications. We aimed to describe the effect of the calcium phosphate product (Ca*P) on FGF-23 concentrations in children and young adults without confounding cardiovascular disease. METHODS Pediatric and young adult patients with CKD sta...

OBJECTIVE. The purpose of this study is to evaluate the ability of two commercial strip tests and laboratory titration to detect saliva buffer capacity. MATERIALS AND METHODS. Sixty-four patients were examined. Stimulated saliva was collected and buffer capacity was determined with two different chair-side strip tests in addition to immediate transportation to the laboratory to check the buffer...

The main objective of this study is to construct and standardize an Attitude Scale measure the B.Ed students towards Teacher Eligibility Test (TET) Assam. researcher used descriptive survey method in present study. selected 496 sample for tryout draft attitude scale TET Assam t-test item analysis TET. 38statements final out 41 items on basis high t-value. For estimating reliability Assam, colle...

In this article we describe a new Hermite series based sequential estimator for the Spearman rank correlation coefficient and provide algorithms applicable in both stationary non-stationary settings. To treat setting, introduce novel, exponentially weighted correlation, which allows local nonparametric of bivariate data stream to be tracked. best our knowledge is first algorithm proposed estima...

We investigated seven distance measures in a set of observations of physicochemical variables of mango (Mangifera indica) submitted to multivariate analyses (distance, projection and grouping). To estimate the distance measurements, five mango progeny (total of 25 genotypes) were analyzed, using six fruit physicochemical descriptors (fruit weight, equatorial diameter, longitudinal diamete...

If a test consists of two parts the Spearman–Brown formula and Flanagan’s coefficient (Cronbach’s alpha) are standard tools for estimating the reliability. However, the coefficients may be inappropriate if their associated measurement models fail to hold. We study the robustness of reliability estimation in the two-part case to coefficient misspecification. We compare five reliability coefficie...

A recent study raised concerns regarding the ability of the health professions admission test (HPAT) Ireland to improve the selection process in Irish medical schools. We aimed to establish whether performance in a mock HPAT correlated with academic success in medicine. A modified HPAT examination and a questionnaire were administered to a group of doctors and medical students. There was a sign...

We propose a copula based statistical method of fitting joint cumulative returns between a market index and a stock from the index family to daily data. Modifying the method of inference functions for margins (IFM method), we perform two separate maximum likelihood estimations of the univariate marginal distributions, assumed to be normal inverse gamma mixtures with kurtosis parameter equal to ...
