Nonlinear methods in physical education is a new idea that covers all the disadvantages of the traditional method and is effective for learning and implementation based on the results of studies compared to the linear method. However, it is not clear how much this method is used by trainers in Iran. This study sought to determine what kind of method (linear / non-linear) instructors use for tra...
A comparative workflow, including linear and non-linear QSAR models, was carried out to evaluate the predictive accuracy of models and predict the inhibition activity of a series of aryl-substituted isobenzofuran-1(3H)-ones. The data set consisted of 34 compounds was classified into the training and test sets, randomly. Molecular descriptors were selected using the genetic algorithm (GA) as a f...
نتایج مطالعات مختلف در طول سال های گذشته به خوبی نشان می دهند که با افزایش تولید شیر، عملکرد تولیدمثلی در گاو شیری دچار افت شده است، که این مسأله می تواند سوددهی واحدهای تولیدی گاوشیر را تحت تأثیر قرار دهد به همین دلیل هدف از انجام این مطالعه بررسی صفات تولیدمثلی در شهرکرد بود. در این پژوهش از 700 رکورد مربوط به 501 تلیسه هلشتاین و 1773 رکورد مربوط به788 رکورد رأس گاو (موجود در 8 و 9 واحد پرورش...
the rational expectations permanent income hypothesis implies that consumption follows a martingale. however, most empirical tests have rejected the hypothesis. those empirical tests are based on linear models. if the data generating process is non-linear, conventional tests may not assess some of the randomness properly. as a result, inference based on conventional tests of linear models can b...
