Question

Suppose you conduct the modified White’s Test. You estimate the regression with the squared residuals as the dependent variable and predicted values and predicted values squared as independent variables. From the regression results, you get the F-statistic is 0.353 with a p-value of 0.414. At a Level of Significance of 5%, what does the modified White’s Test say about the Linear Regression?

Group of answer choices

Heteroskedasticity is unlikely to be a problem with the Linear Regression

Heteroskedasticity is likely to be a problem with the Linear Regression

The coefficients of the Linear Regression are likely biased

The Linear Regression doesn’t have a good Goodness-of-Fit

Answer #1

P-value rule for a two-tailed test:--

if the p-value is less than the alpha/2 then reject the null hypothesis

if the p-value is greater than the alpha/2 then fail to reject the null hypothesis

H0: no heteroscedastic

Ha: heteroscedastic

here, p-value = 0.414

alpha/2 = 5%/2 = 0.05/2 = 0.025

0.414 > 0.025

=> p-value > alpha/2

=> fail to reject null hypothesis

hence no heteroscedastic

hence correct option is A i.e. Heteroskedasticity is unlikely to be a problem with the Linear Regression

8. Calculating SSR, SSE, SST, and R-squared
Suppose you are interested in studying the effects of education
on wages. You gather four data points and use ordinary least
squares (OLS) to estimate the following simple linear model:
wage=β0+β1educ+u
where
wage = hourly wage in dollars
educ = years of formal education
After running your regression, you decide to examine how the
fitted values of wages from your regression compare to the actual
wages in your data set. These data are...

Applying Simple Linear Regression to Your favorite Data (Please
confirm with the instructor the dataset you find before you work on
this question) Many dependent variables in business serve as the
subjects of regression modeling efforts. We list such variables
here: Rate of return of a stock Annual unemployment rate Grade
point average of an accounting student Gross domestic product of a
country Choose one of these dependent variables, or choose some
other dependent variable, for which you want to...

(1) A Chi-squared test is typically used to test for any of the
following except which of the following?
(A) If a mathematical model accurately predicts our observed
frequencies of data values.
(B) If a mathematical model accurately predicts the total number
of observed data values.
(C) If a mathematical model accurately predicts the pattern of
our observed data values.
(D) Whether two factors present in a population are independent
of one another.
(E) Whether a series of populations experience...

Regression Analysis with a Minitab output
Assume that your company owns multiple retail outlets in cities
across the United States. You conduct a study to determine if daily
sales levels (in hundreds of dollars) can be predicted by the
number of competitors that are located within a one-mile radius of
each location and city population (in thousands of people).
Therefore, the dependent variable is SALES and the two independent
variables are NUMBER OF COMPETITORS and CITY POPULATION. Your
research team...
