Random variables

The objectives of this study were to identify promising rice genotypes and evaluate the genetic variance and effectiveness of selection of the rice varieties for several yield attributing traits. A varietal trial of fifteen rice genotypes was laid out in a randomized complete block design (RCBD) with three replications in a farmer’s field in Sundarbazar, Lamjung, Nepal during the rainy season of 2018.

This work aims at investigating the effect of aleatoric uncertainty of creep rock properties on the stability of an underground structure. This uncertainty relates to the spatial variability of the mechanical parameters representing the time-dependent behavior of geological rock formation due to the change in its mineralogy.

Twenty one genotypes including check Krishna were evaluated in randomized block design with three replications during kharif-2017 at research farm of TCA, Dholi for estimation of genetic variability among them. Genotypes varied significantly for all the morpho-physiological characters indicating the presence of considerable variability among the genotypes. Significant bidirectional shift was observed in the mean values as compared to better check, thus provided scope for selection.

A feeding trial was conducted in female parent stock of Swarnadhara for 8 weeks during grower stage. Test diets were formulated at variable levels of energy (2500 / 2400 kcal ME / kg) and protein (16 / 15 % CP) to form 4 treatments (High Energy/High Protein–T1; High Energy/Low Protein T2; Low Energy/High Protein–T3 and Low Energy/Low Protein–T4). 384 grower birds (13 – 20 weeks age) were divided into 32 replicates of 12 birds each to offer four diets randomly to 8 replicate groups under deep litter system.

This paper investigates whether the accuracy of models used in accounting research to predict categorical dependent variables (classification) can be improved by using a data analytics approach. This topic is important because accounting research makes extensive use of classification in many different research streams that are likely to benefit from improved accuracy.

A conventional structure during bearing loads usually has cross-sectional areasoften changed, not always constant because of defectiveness or corrosiveness…Moreover, in the process of working, the loads acting on structures themselves change. Therefore, this paper offers solutions of a truss mentioned the change of cross-sectional areas and loads are modeled as two types of random variables.

Let A be an n × n matrix, whose entries are independent copies of a centered random variable satisfying the subgaussian tail estimate. We prove that the operator norm of A−1 does not exceed Cn3/2 with probability close to 1. 1. Introduction Let A be an n × n matrix, whose entries are independent, identically distributed random variables. The spectral properties of such matrices, in particular invertibility, have been extensively studied (see, e.g. [M] and the survey [DS]).
