This paper addresses the problem of forecasting daily stock trends. The key consideration is to predict whether a given will close on uptrend tomorrow with reference today’s closing price. We propose model that comprises features selection model, based Genetic Algorithm (GA), and Random Forest (RF) classifier. In our study, we consider four international indices follow concept distributed lag a...
In order to study the effect of incomplete sire's pedigree on genetic trend (bBv,y) and gain (R) of quantitative trait, two population were simulated with the heritability 0.15 and 0.30. For each population, information resulted from ten years of selection were saved in different files. In generated data files, the sire numbers were eliminated from pedigree file with 0, 10, 20, …, 100 percentag...
the aim of this study was to estimate the genetic and phonotypic trends of somatic cell score in iranian holstein cows. also, the environmental factors affecting this trait are investigated. a total of 375351 test day records of somatic cells take from 54374 animals between year 2002 and 2007 were used in this study. the breeding values were estimated by fitting animal model in asreml software....
the aim of this study was to estimate the genetic trend and genetic parameters of survival traits in baluchi sheep using survival records from 27978 baluchi sheep, which were collected by the animal breeding center of iran during1979 to 2009. genetic parameters of lamb survival from 1 to 400 days of age and from 1 to the last recording date. traits were estimated using animal model (with or wit...
