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 objective of the current study was to estimate the genetic parameters for body weight traits at different ages in iran-black sheep. data collected during a 24-year period (1984-2008) on body weight were used to model the growth trajectory and estimate genetic parameters. studied traits were birth weight (bw), weaning weight at 3 months of age (ww), 6 months weight (6mw), 9 months weight (9m...
