Regression

Cerebrovascular reactivity (CVR) refers to the change in cerebral blood flow (CBF) in response to a vasoactive stimulus (Kety and Schmidt, 1948). Impaired CVR has been linked with many cerebral and cerebrovascular pathologies (Glodzik et al., 2013; Greenberg, 2006a; Han et al., 2008; Mandell et al., 2008c; Mikulis et al., 2005; Yezhuvath et al., 2012; Zhao et al., 2007), to study the effects of drugs on cerebral vasculature (Pattinson et al., 2007; St Lawrence et al., 2002) and also presurgical…

Results indicated that average reaction times for the auditory and visual stimuli tests were both significantly different from that of the control conditions (see table 1 and figures 1, 2 and 3). Differences in average reaction time differing from the control test (test 1) range from as little as 4 milliseconds (test 2, test subject 2) to that of 67 milliseconds (test 4, test subject 3) (see table 1 and figure 1, 2 and 1.3). According to the averages of the percent increase in reaction time, the…

Fisman and Svensson found some evidence that corruption influences growth at the micro level. They have used the dataset which contains information on the estimated bribe payments of the firms in Uganda. Their dataset contains information from the Ugandan Industrial Enterprise Survey about 243 firms in 5 locations and 14 industries. As it was discussed before, corruption has a very secretive and uncertain nature, and therefore there have been implemented different methods in order to increase…

Balance Balance is evaluated on 7 items. Again, points are administered for independence and strength of performance of individual actions, such as sitting or standing. Maximum score for this section is 14. The Barthel Index of Activities of Daily Living The Barthel scale (reference) is a ten item index assessing patients Activities of Daily Living (ADL) and morbidity, including: absence or presence or faecal and/or urinary incontinence, as well needing help with grooming, toilet use,…

MIS 790 Comprehensive Exam Q1. To be able to build prediction models of botnet attacks, we had to decide information requirements. (a) What process did you use for identifying predictor variables for modelling botnet traffic flows? (b) What additional measures can be taken in terms of information (or data) gathering to further improve the accuracy of the prediction models? (a) I started with a literature survey and read articles to understand the problem and technical terms. To understand the…

Passing-Bablok regression of the LC-MS/MS versus the LIAISON was y=0.65x-0.01, Pearson`s coefficient of correlation r=0.975 (n=175); LCMSMS versus Immulite was y=0.60x+0.21, r=0.746 (n=125), LC-MS/MS versus RIA was y=0.75x+0.01, r=0.956 (n=80); LIAISON versus Immulite was…

A total of four hypotheses were examined using the following variables: feelings of tension and anxiety before and after watching a video in which a news story covered a student going to a college campus with the intent of harming people, perceived threat while watching the video, perceived threat while watching similar news coverages, the number of hours a day spent consuming news, and participant gender. First, to test the hypothesis that feelings of tension and anxiety will be higher after…

From what I have concluded from the two articles listed below, I do not think eyewitness testimony is a reliable source nor should it be used to convict someone simply because mistakes can be easily made. (Clare) 2012 states that mistakes can often be made due to high stress levels, the act of seeing violence and even the display of a weapon can alter a memory of who the witness truly is. Another major issue with misidentification has to do with different racial profiles, seeing other people at…

I enjoyed completing the Project Implicit test and found it to be an interesting assessment. I like that the quiz was based on an automatic response and that pictures or words were assimilated with hidden biases. My skepticism around the test was based on the order the pictures and words were presented. After taking multiple series with pictures on a certain side, and then the pictures reversing, it felt as if the brain was already conditioned to a go to a particular side. My other skepticism…

Logistic Regression model will be used to analyze the research data pertaining to identify the strength of religiosity and how it affects vaccination behaviors among US children age 6 years or less. The Logistic Regression Model would be used in our research because the dependent variable is a categorical variable which is define at two levels (vaccination behaviors). The Logistic Regression model is defined as a statistical analysis that used to measure the risk or odds of an event between the…
