Discriminant Analysis In the question above, we used Logistic Regression to analyze how four variables (number of hours of TV viewing per week, number of detergent purchases last year, gender of head of household, and household income in $k) affect the awareness of 1 CSG. Please use the same dataset to construct a discriminant analysis model and answer the following questions. 4. (10 points) Construct the DA model. How many \"bins\" (or groups of customers) the model has? How many assignment functions? 5. (10 points) Conduct DA analysis in SPSS. Show the classification function coefficient table. Based on the table, what are the assignment functions for the bins? 6. (20 points) Which group the following household is predicted to belong to: watches 25 hours of TV, made 8 detergent purchases last year, female household head, and makes $60,000? 7. (20 points) What are the main differences between the DA model here and the Logistic Regression model? (Note: both models are used for studying essentially the same managerial question here). Note: since the awareness variable has values of 0 (not aware of CSG) and 1 (aware of CSG), please use minimum of 0 and maximum of 1 when defining the range of the grouping variable in SPSS.

Access 2019 Project Exp19_Access_Ch03_CapAssessment - Retirement Accounts 1.3 Project Description: One-Stop Finance is a company that works with clients in all areas of finance. They assist with banking, financial planning, mortgages, stocks, insurance, retirement counseling, and debt consolidation. Cala Hamieh, one of the senior planners for the company, is hoping to extract information from the database. The company has a large database with hundreds of thousands of accounts, but to allow you to rapidly test your queries, you have created a smaller version of the database with a small amount of clients. Once you are confident your queries work, you can import them into the main Access database. Steps to Perform: Step Instructions Points 1. Start Access. Open the downloaded Access file named Exp19_Access_Ch03_CapAssessment_Retirement_Accounts.accdb. Grader has automatically added your last name to the beginning of the filename. 2. Create a query using Query Design. From the Clients table, display the client's FirstName and LastName. From the Accounts table, select the Savings Balance and OpenDate. Sort the query by Savings Balance in descending order. Save the query as Account Longevity. 3. Add a calculated field named AccountTime that calculates the number of days each client's accounts have been open. Assume today's date is 12/31/2019. Recall dates must be enclosed in # to denote to Access it is a date. Format the results in General Number format. Run the query. Close the query. 4. Create a query using Query Design. From the Clients table, display the client's FirstName and LastName. From the Accounts table, select the Savings Balance. Add appropriate grouping so the client's total retirement account savings balances are displayed. Add a sort so the highest total savings balances are displayed first. Switch to Datasheet view. Add a totals row displaying the count of the last name and the average of total savings balances. Save the query as Total Balances By Client, and close the query. 5. Create a copy of the Total Balances By Client query. Name the query Total Balances By State. Open the query in Design view and remove the client name from the query. Add grouping by the client's State. Sort by the client's State in Ascending order and remove the sort on the Savings Balance. Add criteria so clients with retirement account savings balances of $12,000 or more are factored into the query. Switch to Datasheet view. Save and close the query. 6. Create a new query using Query Design. From the Clients table, select the client FirstName, LastName, and State. From the Accounts table, select the Savings Balance. Add criteria so only customers with balances under $13,000 are displayed. Add a new field named LoanPayment using the Expression Builder. Insert the Pmt function to determine the monthly payment for a 2-year loan, paid monthly, with a 5% yearly interest rate. The present value is 25000 minus the Savings Balance. For example, if the purchase price were 25000, with 5000 in savings to put toward the purchase, your present value would be 20000. Ensure the number displays as a positive number. Change the format of the LoanPayment field to Currency. Change the caption to Loan Payment. Run the query. Save the query as Monthly Loan Payments and close the query. Date: 07/12/2019
