Receiver operating characteristic

organization structure with highly routine operating tasks achieved through specialization, very formalized rules and regulations, tasks that are grouped into functional departments, centralized authority, narrow spans of control, and decision making that follows the chain of command,” (Robbins & Judge, 2011. p.…

This layer provided the interface between applications used on the computer. Protocols such has Telnet, FTP, HTTP, SMTP etc are used on this layer. There aren 't any special devices operating in this layer, just the actual computer itself. Layer 6 which is presentation layer in OSI model helps with formatting of the data, for example if you are sending email, presentation layer will format data into email format which can be understood…

regression to identify independent predictors of substantial intraoperative blood loss (i.e., > 60 mL/kg) and the need for coagulation products with the c-index used to judge the quality of model prediction and the Youden J-index in receiver operating characteristic (ROC) curve analysis to determine the optimal cut-off values for TEG parameters and the platelet fibrinogen product.{Katz, 2011 #408} We developed a ROC curve based on a simplified predictive algorithm according to the number of…

effective way to win a campaign.”(85) As a consequence, gathering data on voters to determine the amount of votes that are needed to win a campaign is critical to the success model. Demographics also play a key role in terms of using certain characteristics about an individual to determine the likelihood of them voting for your political party. For example, African Americans and women typically vote Democratic and therefore it would be imperative for a progressive campaign to target those…

Current Industry Landscape: According to the Exhibit 5, today China is the world’s largest car manufacturer responsible for 26% of total production. Kenya is on the opposite end with only 3,080 cars being produced annually. China, India and Kenya are comparable in terms of labor costs. If GM facilitates production in Kenya, then it would have an easy access to the resources and cheap labor; while in China and India it would have to compete for the same resources with a large number of domestic…

Police lineups are performed everyday, but do the right suspects always get picked? Witnesses rely their memories involving the suspect, like what was their eye color, hair color, how tall or short where they, how much they weigh, and was it a male or female. Sometimes these memories do not always benefit the witness during their decision making. A police lineup is going to be made of one suspect, and many others not involved in the case. There are three different types of lineups used in this…

Preservation for a kidney can be up to 72 hours while a heart can only be preserved for five to eight (Landesman). Currently, when an organ becomes available, many factors are reviewed to find the most suitable receiver: blood and tissue typing, medical urgency, geographical location, and length of time on the waiting list. First, the local waiting list is reviewed for these elements. If no one is in need at the local level, it is reviewed at the regional level…

annual survival was observed for 12-20 years. Scientists have used Cormack-Jolly-Seber-Open- population models in the program MARK to estimate apparent survival. Variance-component module program MARK to estimate variation in survival. Climate data was collected by using PRISM maps for monthly minimum and maximum temperatures and also seasonal data was collected from GIS, NCDC. Scientists have applied Palmer drought severity index to assess moisture levels during the season. To assess region…

Health-related quality of life (HRQoL) is an evaluation of how the individual’s well-being may be affected over a period of time by a disease, disability or disorder. There are two types of HRQoL instruments; generic HRQoL instruments and disease-specific HRQoL instruments. Generic HRQoL instruments consist of the multi-attribute utility instruments (MAUI). Generally, MAUI comprises of many sub-instruments such as EQ-5D, HUI, and SF-6. The EQ-5D defines health according to five dimensions which…
