In the interest of business innovation, social network companies often carry out experiments to test product changes and new ideas. such experiments, users are typically assigned one two experimental conditions with some outcome observed compared. this setting, user may be influenced by not only condition which they but also other via their connections. This challenges classical design analysis...

We immediately notice the similarity between the empirical risk we had seen before and the negative loglikelihood. We will see that we can regard maximum likelihood estimation as our familiar minimal empirical risk when the loss function is chosen appropriately. In the meantime note that minimizing (1) yields our familiar square-error loss if Wi’s are Gaussian. If the Wi’s are Laplacian (pW (w)...

in this study, the effect of maternal additive genetic and environment on body weight at 6 weeks (bwt6w), breast width (hbrs), carcass weight (carcwt), breast weight (brswt), blood hematocrit value (hem), residual feed intake (rfi), daily feed intake (dfi) and average daily gain (adg) were investigated in a commercial broiler dam line. with and without maternal effects, six different animal mod...

in this research, 6517 records, collected by khojir sheep breeding station (tehran, iran), during 1991 to 2011 were used to estimate genetic parameters of lamb survival in zandi sheep. genetic parameters were estimated using 16 different models of animal model, sire and threshold models using reml procedures. the aic criterion was used to evaluate the models. the effects in the most suitable an...

     Improved drought-tolerant maize hybrids would significantly reduce water consumption and increase yield in arid environments. Our knowledge about genetic parameters is very essential before starting a successful breeding program. The present research was carried out throughout three successive years between 2013-15 to reveal the pattern of inheritance in yield, yield-components and related...

Within a type of additive processes of finite jump activity (FJA), we give precise conditions for the mean-squared consistency and the validity of a feasible Central Limit Theorem for thresholded realized power variation estimators (TRV). The obtained results show that some conditions commonly used in the literature are rather strong and far from being necessary. To justify that the proposed co...

in order to study of combining ability and heterosis in cotton (gossypium hirsutum l.), six hopeful genotypes were crossed in a half-diallel scheme at gonbad research station. fifteen f1 hybrids along with six parents were grown in randomized complete block design with 3 replications, in 2004. combining ability estimates were calculated according to method 2, model 1 of griffing (1956a,b). rela...

influence of maternal and sire-generation interaction effects on day-old chick' weight was investigated in two commercial broiler sire and dam lines, and in mazandaran native fowls. the data were analysed through restricted maximum likelihood (reml) procedures, using asreml software. ten different animal models were implemented and compared with likelihood ratio test. all models consisted ...
