The binary logistic regression model (LRM) is practical in situations when the response variable (RV) dichotomous. maximum likelihood estimator (MLE) generally considered to estimate LRM parameters. However, presence of multicollinearity (MC), MLE not correct choice due its inflated standard deviation (SD) and errors (SE) estimates. To combat MC, commonly used biased estimators, i.e., Ridge est...

DEA methodology allows DMUs to select the weights freely, so in the optimalsolution we may see many zeros in the optimal weight. to overcome this prob-lem, there are some methods, but they are not suitable for evaluating DMUswith fuzzy data. In this paper, we propose a new method for solving fuzzyDEA models with restricted multipliers with less computation, and comparethis method with Liu''''''...

Facebook is the most dominant social networking site in colleges right now. According to a recent study done by OnlineEducation.net on college students' use of social media in the U.S., 96 percent of college students use Facebook. In addition, 75 percent of college students report that they want to collaborate online with each other via Facebook (Andrew, 2011). Because of the popularity of Face...

fundamentally from its desktop or Internet counterparts. Embedded computing is not simply computation on small devices. In most control applications, for example, embedded software engages the physical world. It reacts to physical and user-interaction events, performs computation on limited and competing resources, and produces results that further impact the environment. Of necessity, it acqui...

state estimation is the foundation of any control and decision making in power networks. the first requirement for a secure network is a precise and safe state estimator in order to make decisions based on accurate knowledge of the network status. this paper introduces a new estimator which is able to detect bad data with few calculations without need for repetitions and estimation residual cal...

The prevalence of Toxoplasma gondii infection in free-range chickens in Jilin province, northeastern China was investigated. A total of 1095 serum samples were collected from nine administrative regions from July to October, 2012, and antibodies to T. gondii were examined by an in-house enzyme-linked immunosorbent assay (ELISA) using Toxoplasma lysate antigen (TLA). The detection results were c...

Let be a random sample from a normal distribution with unknown mean and known variance The usual estimator of the mean, i.e., sample mean is the maximum likelihood estimator which under squared error loss function is minimax and admissible estimator. In many practical situations, is known in advance to lie in an interval, say for some In this case, the maximum likelihood estimator...
