STAT 758: Homework #6 Due on Wednesday‚ 11 April‚ 2012 Zaliapin‚ 1:00pm Tracy Backes 1 Tracy Backes STAT 758 (Zaliapin): HW #6 Problem #1 We assume below that Zt ∼ W N (0‚ σ 2 )‚ B is a backshift operator. 6.1 For the model (1 − B)(1 − 0.2B)Xt = (1 − 0.5B)Zt : a) Classify the model as an ARIMA(p‚ d‚ q) process (i.e. find p‚ d‚ q). ARIMA(1‚1‚1) b) Determine whether the process is stationary‚ causal‚ invertible. • The process is stationary if all roots of ϕ(z) are off of the unit

processes of science and technology. The public understanding of measurement errors and confidence intervals could be enhanced if `sports-decision aids’‚ such as the Hawk-Eye system‚ were to present their results in a different way. There is a danger that Hawk-Eye as used could inadvertently cause naïve viewers to overestimate the ability of technological devices to resolve disagreement among humans because measurement errors are not made salient. For example‚ virtual reconstructions can easily be

of this simulation to obtain important parameters of a bank queue‚ including bank information‚ queue length‚ waiting time in queue and expected wait time of customers in a bank. To obtain the appropriate function for predicting the queue waiting time we need a large numbers of observations. To obtain this data without the need to collect them directly‚ we simulate the bank work flow and after ensuring that the model built reflects the actual situation‚ we use the output data and simulations for prediction

Download and Installation of NS-2 in a Linux/UNIX environment NS2 is a network simulator program; it is freely available on the internet to download for academic research purpose. NS2 can be compiled and run both in a UNIX and under Cygwin for windows environment. It is an important to note that NS2 is fairly large and requires around 300 MB hard disk space for installation. In order to run and install NS2 you need a PC with a C++ compiler and UNIX operation system (FreeBSD‚ Linux‚ SunOS‚ or Solaris)

“Careful‚ #517908. Remember‚ you don’t want them to find out they’re living in a simulation‚” said Zoidberg‚ from the comfort of the engineering headquarters somewhere in a distant universe. “If they do‚ we might have to pull the plug.” However‚ this was merely a distant concern for both. Tired of how slow the human species were progressing compared to his other simulations‚ Zoidberg came up with an idea: give them a stat boost in the form of a software update. HumanOS 2.0‚ he (rather unoriginally)

On Friday July 15‚ my group of medical student visited the simulation laboratory. After climbing a couple sets of stairs we were broken off into three different groups for three different sets of activities. The first for me a combination of a couple of simulations. The first one was a simulation designed to help surgeons further develop their skills. We used small clamps to pick up and move rings to different poles. This seems quite simple but we had to do it looking at a monitor that projected

sample size of the experiment is 3‚ which means every different increase of probability of infection was tested three separate times. It is desirable to increase the sample size of an experiment‚ because it decreases the amount of random and systematic errors made. It also provides more reliable and more accurate results‚ because you are testing that probability more times. During the experiment and the write up of this practical I believe that I managed to work collaboratively and successfully work

1. Playing this simulation has helped me understand the interdependent nature of organizational change management. It has highlighted the complex nature of change management that every director or executive must face to keep all the employees of the company onboard. They must do their best to keep the employees together though it may so appear that the employees do not seem to easily agree with one another. Also‚ the discrepancies between the middle-level and tactical-level employees could be though

Medical Errors Medical errors are avoidable negative effects of care‚ which can be harmful to a patient. These errors can vary from giving the wrong treatment to a disease‚ injury‚ syndrome‚ behavior‚ or infection a patient might have. Nurses play one of the most important roles in the avoidance of occurring medical errors. By doing their job correctly they can prevent the errors from happening and potentially hurting or killing a patient. Decimal errors‚ trailing zero errors and abbreviation errors
