managerial economics 2

Vicky help me, Is the sentense as below right ? Linear model is a better job of fitting the data because the value of R1 and R2 of linear model is greater than that of log model. The more the value of R1 and R2 is near 1, the more regression model can explain the total variation. In this case, linear model can explain more than 50% of the total variation. Likewise, since the value of F-statistic of linear model is larger than that of log model, so simple linear model is better model. From the equation, when the income Y decreases, the price will decrease and the demand curve will shift to the left. Q value matches my economic intuition because marginal price is positive and greater than 0. The price relatively has a lower effect on the quantity demanded because the coefficient on the log of price is lower than that of original price. The 95% confidence interval for the coefficient on price is between -10 and -5.

Hi there [이름]! I know that you are having a hard time with your Managerial Economics now. However, don\'t worry too much about it because you will certainly get used to it. You will eventually learn how to express your ideas in English. Just relax and enjoy listening to your American professor. ^^ Teacher Vicky Here are my corrections for you: Vicky help me, Is the sentense as below right ?>> Teacher Vicky, help me. Are the sentences below right?Linear model is a better job of fitting the data because the value of R1 and R2 of linear model is greater than that of log model. >> It is better to use linear model with this data because the values of R1 and R2  are greater than that of the log model. The more the value of R1 and R2 is near 1, the more regression model can explain the total variation. >> The higher the values of R1 and R2, the neaner they are to 1. The regression model can explain the total variation. In this case, linear model can explain more than 50% of the total variation. >> CORRECT!Likewise, since the value of F-statistic of linear model is larger than that of log model, so simple linear model is better model.>> Linear model is better than log model because the value of F is larger than that of the log model. From the equation, when the income Y decreases, the price will decrease and the demand curve will shift to the left. >> From the equation, when income (Y) decreases, price will decrease and the demand curve will shift to the left.Q value matches my economic intuition because marginal price is positive and greater than 0. >> Q value matches my economic intuition because marginal price is positive and it\'s greater than 0.The price relatively has a lower effect on the quantity demanded because the coefficient on the log of price is lower than that of original price. >> The price has a lower effect on the quantity demanded because the coefficient  of price on the log model is lower than the original price. The 95% confidence interval for the coefficient on price is between -10 and -5. >> The 95% confidence interval for the coefficient of price is between -5 and -10.
