Question

Transcribed Image Text:You are hired by a bank to help determine its lending standards. You decide to start by estimating a
simple linear regression model to help predict whether a loan will become past-due (i.e. if any of the
payments are tate).
You ask the bank to give you data on the following two random variables:
PD is an indicator variable equal to 1 if the loan is past-due, and zero if all payments have been made
on time.
credit score is the client's credit score at the time the loan was originated.
The table below shows sample descriptive statistics for these variables:
Variable
PD
credit_score
Sample Mean
0.1
Sample Standard Deviation
0.08
550
25
The sample covariance between PD and credit score is -0.9
Use OLS to estimate the following simple linear regression model: PD = Bo + Bicredit_score + u
Round your answers to four decimals.
What should be the average value of the credit score among the bank's clients if the banks wants to
have a predicted share of past due loans equal to 0.05 (i.e: 5%)? Round your answer to the nearest
integer.

Transcribed Image Text:You realize that a person's credit score is affected when they default on a
loan.
If you estimate the following linear regression model instead
credit_score =
Bo + B1 PD+ u, then the value of the coefficients
estimated using OLS would be the same as those you estimated in the
previous question, because both models use the same random variables.
O True
O False

The state collected information on a random sample of high school seniors from across the state 7 years ago and is now observing how many years of education they completed. They believe students decide to achieve more education when they are more capable, have easier access to college education, and the opportunity cost of attending are lower. To explore the factors that affect the years of education completed they have used multiple regression to estimate the years of completed education as a function of: Unemployment rate - the unemployment rate in the county (3.9 – 16.8) County Hr Wage - average starting hourly manufacturing wage in the county Test - student score on college admission test (0 to 100 scale) Dist to college - Distance to near college (measured in 100’s of miles) Tuition - Tuition charged at nearest state university (measured in $1000s)…arrow_forwardExplain about the least square regression line?arrow_forward
- Which statement is not correct for multiple regression model? When we interpret this categorical variable, we would say the change we observe when one switches from the reference category to the specific category. The reference category will not be displayed in our model results. If we include a categorical variable with more than two values (e.g., religion) as an independent variable, we want to include a dummy variable for all categories except for two. We can include more than two categorical variables in the model. The value of the independent variable not included in the model is called "reference category."arrow_forwardTo properly examine the effect of a categorical independent variable in a multiple linear regression model we use an interaction term.

- You plan to fit a regression model that will be used to predict first-year college GPA (FYGPA) from high-school GPA (HSGPA), ACT score (ACT), first-generation status (Yes or No), socioeconomic class (lower class, lower to middle class, middle to upper class, and upper class), and school type (public or private). What is the total number of estimated regression coefficients?

A family purchases a 2000 square foot home and plans to make extensions totalling 500 square feet. The house currently has a pool, and a real estate agent has reported that the house is in excellent condition. However, the house does not have a view, and this will not change as a result of the extensions. According to the results in column (1), what is the expected DOLLAR increase in the price of the home due to the planned extensions?arrow_forwardYour state is going to vote on becoming a "right to work" state in the next, and you wonder if there is there a relationship between salary levels and unionization. You find data on salary from the U.S. Census, which is split into three groups: Low; Moderate/About Average, and; High. To see if salary, measured in this way, is associated with unionization you find a variable in the same dataset called "UNION", which has two categories: the respondent has a unionized job and the respondent does not have a unionized job. Because you want to know if you should favor or oppose becoming a "right to work" state, you test these two variables to see if there is an association between salary level and unionized labor. What type of hypothesis test is most appropriate?arrow_forward
- Provide an example of a regression that arguably would have a high value of R² but would produce biased and inconsistent estimators of a causal effect. Explain why the R² is likely to be high. Explain why the OLS estimators would be biased and inconsistent.arrow_forward18)The regression equation is intended to be the “best fitting” straight line for a set of data. Whatis the criterion for “best fitting”?arrow_forwardA small independent organic food store offers a variety of specialty coffees. To determine whether price has an impact on sales, the managers kept track of how many kilograms of each variety of coffee were sold last month. The data and summary statistics (including the averages, standard deviations and the correlation coefficient) are shown in the table. If the "price per kilogram" is the predictor variable and "kilograms sold" is the response variable, then use a regression line to predict the the amount of kilograms sold for a "price per kilogram" equal to $15. Round your numbers to 3 decimal places.arrow_forward
