IntroductionThe Primary goal of the project is for students to gain comfort in using statistical software packages to conduct an empirical analysis of a particular firm. Specific goals are for students to (1) become familiar with sources of economic and financial information and in particular the Wharton Research Data Services (WRDS) Database, (2) practice their writing skills, (3) develop hands on, statistical estimation and modeling skills using excel (e.g., data analysis, regression analysis). The project is an individual assignment and late submissions will not be accepted. Please provide explanations for answers to all questions.Background material: Chapter 4, 5 in McGuigan, Moyer and HarrisPLEASE FIRST SELECT PUBLIC COMPANY TO ANALYZE. USING YOUR WEB BROWSER, ANSWER ALL OF THE QUESTIONS THAT FOLLOW FOR THAT PARTICULAR COMPANY. THE CHOICE OF COMPANY IS UP TO YOU. BUT, PLEASE EMAIL ME TO LET ME KNOW OF YOUR SELECTION AND MAKE SURE THAT YOU HAVE ENOUGH DATA TO ANSWER ALL OF THE QUESTIONS. COMPANY SELECTION IS FIRST COME FIRST SERVE. IT IS A GOOD IDEA TO KEEP THREE OR FOUR COMPANIES IN MIND BECAUSE YOU ARE TO FIND A COMPANY THAT HAS ENOUGH PUBLICALLY AVAILABLE DATA TO ANSWER EACH QUESTION. THERE IS NO NEED TO INCLUDE DATA OR SPECIFIC PROGRAMS USED TO ANSWER QUESTIONS, BUT, IN ALL YOUR RESPONSES, PLEASE INCLUDE EXPLANATIONS OF STEPS CARRIED OUT. IT IS OKAY TO WORK WITH OTHER PEOPLE, BUT YOUR EXPLANATIONS SHOULD BE IN YOUR OWN WORDS.1. Data collection from WRDS databaseUsing your web browser, please go to the WRDS URL (http://wrds.wharton.upenn.edu) and collect data on the variables for the risk free rate, small minus big, high minus low, and the excess market return for the firm your selected. When you collect the data, please select the monthly frequency and the range spanning from 1980 through 2017. Using your class notes and the descriptions provided by WRDS, please provide a brief description of each variable included in the study. Please save these variables in an excel spreadsheet. Please download and save stock prices for your firm spanning the same period and at the monthly frequency. Please compute stock price returns as the ratio of the change in the stock price for each period with respect to the previous period to the value in the previous period This will serve as the base case from which we will complete the rest of the project.2. Regression AnalysisFor this question, you will need the data analysis tool pack in excel, please download it to your version of excel for your operating system before answering the questions listed below.a.Please, separately, determine the estimated regression line for a regression with the stock return as the dependent variable and the following list as independent variables:a.Excess market returnb.Small minus bigc.High minus lowb.Please determine the estimated regression line with the stock return as the dependent variable and the risk free rate, excess market return, small minus big, and high minus low as the independent variables in one single regression model.c.Which regression coefficients are statistically significant? Is the overall model significant?d.What is the adjusted R-squared for the model? How does it compare to the adjusted R-squared for each model estimated in a? Is your answer to part b different from your answers to part a? Why or Why not?3. Forecastinga.Using only data covering the period 1980 through 2000, please determine the estimated regression line with the stock return as the dependent variable and the risk free rate, excess market return, small minus big, and high minus low as the independent variables in one single regression model.b.Please use the model to predict stock price return from 2001 to 2017 and compute the root mean squared error using the deviation between the actual stock price return over this period and the model-predicted stock price return over the same period.4. DiscussionUsing your web browser and your own judgement and your class notes, please interpret and discuss the strength of the relationship between stock price returns for your firm and each of the three variables. In particular, please consider whether or not you think that the three variables do a good job in explaining and predicting stock returns for your firm. Please also explain why you think the model produced all results from questions 2 and 3 that it did

Discover Evidence Based Data Used in Clinical PracticeDiscover Evidence Based Data Used in Clinical PracticePurpose:This Assignment is helpful in developing the groundwork for understanding and integrating evidence-based practice in healthcare throughout the rest of the course. In this Assignment you will have the chance to see how the research you look for can be applied in the work you do in your practice.Overview:You will select a topic relevant to your practice area, post the topic to Discussion Board 2 for feedback, research the topic, and write a scholarly paper.From the chapter readings and discussion, formulate a 3–5 page scholarly paper in APA format, providing an overview of the terms and function of EPB. An introduction, discussion and conclusion is expected in the overview on this topicDirections:Formulate the question.Using the Cochrane database, research the question using the PICOT model and key words.Post your topic and a short summary of results for feedback from your instructor and peers by Day 5.Write a 3–5 page paper, reviewing evidence-based practice, as it relates to your practice question and integrate feedback from the instructor and/or peers.Include a minimum of three evidence-based references.To view the Grading Rubric for this Assignment, please visit the Grading Rubrics section of the Course Resources.Assignment Requirements:Before finalizing your work, you should:be sure to read the Assignment description carefully (as displayed above);consult the Grading Rubric (under the Course Resources) to make sure you have included everything necessary; andutilize spelling and grammar check to minimize errors.Your writing Assignment should:follow the conventions of Standard English (correct grammar, punctuation, etc.);be well ordered, logical, and unified, as well as original and insightful;display superior content, organization, style, and mechanics; anduse APA 6th Edition format.Please see the Writing Center located in the Academic Success Center in the student portal for assistance with writing, APA, and online communication. https://campus2.purdueglobal.edu/page/writing-centerRapid Critical Appraisal to Evaluate EvidenceRapid critical appraisal is the opportunity to review evidence in a timely fashion. The ability to look at evidence and review it in a timely fashion will help your practice. You will learn how to look at the evidence that is returned from your database search, and identify what level of evidence is available from your search. For example, being able to identify that a randomized control trial is a reliable source of evidence, rather than an expert’s opinion.Five Components of a PICOTRecognizing the five components of PICOT questioning is the most pivotal aspect of evidence-based practice. Through PICOT, you can determine the patient population that you are working with, the intervention that you propose (based on the research), a comparison intervention and then review the outcome and the time it takes to reach the outcome. For example, determining how long it takes for the evidence-based intervention to improve the quality of life of a patient with terminal cancer.P = patient, population, or problemI = intervention, risk factor, assessment tool, or prognostic factor under scrutinyC = comparison (alternative to intervention; at times this element may be absent)O = outcomeT = time (Is there a certain period of time that must transpire for the intervention to produce an outcome? At times this element may also be absent.How to Identify the Corresponding Research Design for the Foreground QuestionAs you develop a PICOT format, you decide what research design you will use that best meets the needs of your clinical question. For example, if the intervention is a medication, then a case control study would be ideal to determine if the medication is effective compared to patients that do not receive the medication.How to Identify the Corresponding Research Design for the Foreground QuestionYou will be able to identify the importance of evidence, recognizing that expert opinion and clinician opinion are the lowest level of evidence, with meta-analysis and randomized control trials at the top of the hierarchy.Difference Between Foreground and BackgroundForeground and background information must be distinguished for effective evidence-based PICOT development.Foreground information can be answered based on scientific evidence about diagnosing, treating, or even assisting patients. This would be the actual clinical question being researched. So, for example, the question of which analgesic works best to reduce a fever in a child would be foreground informationBackground information is broader in scope as it helps develop the foreground question. For this example on analgesic questioning, the background information would be “how do analgesics work in children?”
