QUESTIONS QUESTION 1: Run Q on the regressors: P (price)‚ I (income)‚ other variables and lagged Q to capture habit forming. Skip the first row because of the empty cell in this row. From the regression output‚ write down the estimated linear demand equation with t-statistics under the estimated coefficients. In addition‚ write down the R-square? Statistical significance of T-statistics is given by the P-values. There are three levels of significance: 1%‚ 5% and 10%. Ignore the P-values

Bufn758Q—Quantitative Investment Strategy Name & Student ID #:_____________________ Professor Wermers Spring 2010 Numeric Investors 1. Briefly discuss the two momentum strategies of Numeric Investors. First approach – Based on past changes in analysts’ estimates‚ where they would cluster their forecasts of company earnings‚ and would revise their earnings estimates incrementally instead of big jumps. This would force analysts to update their estimates and would make consensus estimates

The management are hoping to identify the key drivers of hotel profitability and to use these to help choose their next hotel location out of a few options currently available. For this purpose they require you to build a regression explaining hotel occupancy rates and have identified and collected the following variables for each of the 80 sampled hotels with the data based on

market. Use a spreadsheet or a calculator with a linear regression function to estimate beta. Beta = .62 B. Give a verbal interpretation of what the regression line and the beta coefficient show about the stock Y volatility and relative risk as compared with those of other stocks. The .62 regression line beta estimate for Stock Y shows the relationship with NYSE stocks‚ each time NYSE move up a unit‚ stock Y moves up by .62. This regression line beta estimate for Stock Y also indicates that it

1. This problem is in reference to students who may or may not take advantage of the opportunities provided in QMB such as homework. Some of the students pass the course‚ and some of them do not pass. Research indicates that 40% of the students do the assigned homework. Of the students who do homework‚ there is an 80% chance they will pass the course. The probability of not passing if the student does not do the home work is 90%. What is the probability of a student not doing homework or
