Multiple logistic regression in action, statistics homework help
Assignment: Multiple Logistic Regression in ActionUse the Week 7 Dataset (SPSS document) from the Learning Resources area to complete this assignment. Variables and variable selection Use a table to list the variables, Sex, Age in Years, Serum Cholesterol, Obese, and Hypertension, and each of their levels of measurement. Create new variables Age_Cat and Chole_Cat: Age_Cat: Convert Age in Years into a categorical variable with 2 categories, Less than 40, 40 and greater Chole_Cat: Convert Serum Cholesterol into 3 categories, Under 200, 200-299, and 300 and greater Add the new variables to each record by coding the responses to the original variable using the assigned categories. Be sure that the variable view in SPSS has the correct information on the 2 new variables. Simple Binary Logistic Regression Use Hypertension as the dependent variable and Chole_Cat as the independent variable in the first model. Report the Odds Ratio and significance of the Odds Ratio for the relationship between the dependent and independent variables. Use Hypertension as the dependent variable and Serum Cholesterol (the original variable) as the independent variable in the second model. Report the Odds Ratio and significance of the Odds Ratio for the relationship between the dependent and independent variables. How does the level of measurement for the independent variable affect the outcome (include the OR and its significance in your response)? How does the level of measurement of the independent variable change your interpretation of the Odds Ratio? Multivariate Logistic Regression Run a multivariate binary logistic regression model using SPSS and Hypertension as the dependent variable, Chole_Cat, Age_Cat, Obese, and Sex as the Covariates. Include the output in your submission. Identify the Odds Ratio and the significance of the Odds Ratio for each of the covariates. How has the relationship between Chole_Cat and Hypertension changed with the addition of the other variables (compare to the output from # 2a)? Test the assumption that the model fits the data using the Hosmer-Lemeshow Goodness of Fit test. Interpret the Chi Square statistic given in the output of this test and state what it means in terms of the assumptions needed to use logistic regression with this data. Rerun the logistic regression model from #3a and use the save function to create the following new variables: Predicted Probabilities, Deviance Residuals, and Cook’s Distance. Evaluate the model using these saved variables and the following Scatter Plots. Create a Scatter Plot of the Deviance Residuals (DEV) and the variable ID: Are there any outliers? What does this mean when evaluating your model? Create a Scatter Plot of Cook’s Distance (COO) and the variable ID: Are there any influential cases? What does this mean when evaluating your model? Create a Scatter Plot of Deviance (DEV) and the Predicted Probabilities (PRE). Discuss whether anything in this scatterplot could cause you some concern in terms of your model.

Harward International College Annual return of both J&J and IBM Questions
No plagiarism, follow instructions attached,Question 1 As companies grow in size, it is inevitable for the shareholders to hire management to run the operations of the business. The entire team of management, starting from the CEO and other top-level management, all the way to the middle and bottom level management are expected to perform towards the growth of the business. Since the shareholders of large companies are scattered across geographies, they appoint certain members as representatives who are elected to represent them on the company board. The board of directors of a company, along with the Chairman, are expected to keep the actions of the management in check. Explain the above in context of agency theory and corporate governance. What can companies do to ensure adequate corporate governance?Question 2 Mr. Morris had $100,000 in his account. Using this fund, he made a portfolio of two NYSE listed stocks – Johnson and Johnson (J&J) and IBM on 01 Jan 2019 in the ratio of 60:40, i.e. 60% funds in J&J & 40% funds in IBM. The daily stock data of both stocks can be found on market websites such as finance.yahoo.com. Download daily data for 1 year from 1 Jan 2019 – 1st Jan 2020. Using the stock data of the two stocks, you are required to explain the below concepts and then compute for the given stocks: a. Annual return of both J&J and IBM. (10 marks) b. Annualized standard deviation of returns of both J&J and IBM (10 marks)c.Correlation coefficient of returns of J&J and IBM. What does this correlation coefficient signifyabout the correlation of the two stocks and corresponding decision from an investor? (10 marks) d. Portfolio return of the portfolio of two stocks. (10 marks) e. Portfolio risk (standard deviation) of the portfolio of two stocks. (10 marks)f. Critically analyze your investment decision in these two companies (10 Marks). Given an option, would you like to invest in any other company? Or would you like to have a different ratio of investment in the two? (10 marks)Question 3: Your firm’s geologists have discovered a small oil field in New York’s Westchester County. The field is forecasted to produce a cash flow of C1 $2 million in the first year. You estimate that you could earn an expected return of r 12% from investing in stocks with a similar degree of risk to your oil field. Therefore, 12% is the opportunity cost of capital. What is the present value? The answer, of course, depends on what happens to the cash flows after the first year. Calculate present value for the following cases: a. The cash flows are forecasted to continue for 20 years only, with no expected growth or decline during that period (5 Marks) b. The cash flows are forecasted to continue for 20 years only, increasing by 3% per year because of inflation (5 Marks) c. Evaluate the cashflows in a and b and explain which one you will choose and why (10 Marks)
