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

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
