PURPOSE This study aimed to investigate the relationships between body mass index (BMI) and prostate-specific antigen (PSA) levels, international prostate symptom score (IPSS), quality of life (QoL), and prostate volume (PV). MATERIALS AND METHODS Height, weight, PSA levels, PV, and IPSS were analyzed in 15,435 patients who underwent a prostate examination between 2001 and 2014. Patients aged...
This paper, one in a series on estimation with correlation coefficients, shows how to use any correlation coefficient to produce an estimate of location and scale. Since the normal distribution is so widely used, the method is illustrated using this distribution. Analyzers of normal data are advised to graph a quantile plot to check on the normality assumption before performing their data analy...
OBJECTIVES Volume is an important feature in the evaluation of hypertrophic scars and keloids. Three-dimensional (3D) stereophotogrammetry is a noninvasive technique for the measurement of scar volume. This study evaluated the reliability and validity of 3D stereophotogrammetry for measuring scar volume. STUDY DESIGN AND SETTING To evaluate reliability, 51 scars were photographed by two obser...
â â â â â â â â â â â â abstract â the foreign exchange market (fx market) accounts for 40% of the total volume of the worldâs e-commerce by its own. based on statistics, sometimes up to 90 per cent of the traders lose their total capital in this market just within six months to one year and leave this market. the probability of loss in the fx market can be estimated by probability theory....
Sustainable agricultural practices (SAPs) that lead to an increase in productivity are central to the acceleration of economic growth; this will alleviate poverty and help to overcome the recurrent food shortages that affect millions of households in Africa. However, the adoption rates of SAPs remain below expected levels. This paper analyzes the factors that facilitate or impede the probabilit...
AIMS To evaluate the accuracy of measurement of hepatic venous pressure gradient by catheter wedge as compared to balloon wedge (the gold standard). MATERIALS AND METHODS Forty-five patients having a clinical diagnosis of intrahepatic portal hypertension were subjected to the two different types of pressure measurements (catheter wedge and balloon wedge) during transjugular liver biopsy under...
Bousquet-Mélou and Petkovšek investigated the generating functions of multivariate linear recurrences with constant coefficients. We will give a reinterpretation of their results by means of division theorems for formal power series, which clarifies the structural background and provides short, conceptual proofs. In addition, extending the division to the context of differential operators, the ...
ordering of the parts then this number reduces to the classical Stirling number of the second kind (see [3], p. 244). Often it is the case where there is a constraint on the size of the parts. For instance, consider ordered m-partitions of n where each part must be of size between 1 and N for some constant N ≥ 1. There are known recurrences for the number of such constrained ordered partitions ...
