Regression Interpretation
This assignment is intended to provide you practice conducting regressions in R and interpreting the regression output. Together with this Phrase file in the Assignment in Canvas, you will discover an Excel file with the information wanted to full this assignment, and one other Phrase file with the regression equations to use. Don’t copy and paste from R and RStudio. Assemble your solutions as if you have been making ready a report for a supervisor. When submitting your assignment, embody a Phrase file together with your solutions to the questions and an R Script file with the code you used to full the assignment. This assignment is due by 11:59PM, March 6, 2022, and is to be submitted by way of Canvas.
1. Load the information into R. (No documentation wanted for this half)
2. With the full information body, run the regression equation for absolute worth irregular accruals. In a desk report the coefficient estimates, the t values, and p values for the intercept and the impartial variables. Below this desk report the adjusted R-squared. How a lot of the variation in absolute worth irregular accruals do the impartial variables clarify? Which impartial variables are statistically vital? Which impartial variables are related to greater values of absolute worth irregular accruals? Which impartial variables are related to decrease values of absolute worth irregular accruals?
three. With the full information body, run the regression equation for the pure log of audit charges. In a desk report the coefficient estimates, the t values, and p values for the intercept and the impartial variables. Below this desk report the adjusted R-squared. How a lot of the variation in the pure log of audit charges do the impartial variables clarify? Which impartial variables are statistically vital? Which impartial variables are related to greater audit charges? Which impartial variables are related to decrease audit charges?
four. Absolute worth irregular accruals is a measure of audit high quality. The upper the quantity the poorer the audit high quality. The nearer that quantity is to zero the higher the audit high quality. The pure log of audit charges in a measure of the audit charges paid. Larger values point out greater audit charges have been paid. The impartial variable of curiosity for this mannequin is PCAOB. PCAOB is an indicator variable valued 1 if the audit agency for the firm is registered with the Public Firm Accounting Oversight Board (PCAOB) in the U.S. and valued at zero if the audit agency for the firm is not registered with the PCAOB.
(a) What does the first regression say about the audit high quality of corporations audited by corporations registered with the PCAOB in contrast to corporations audited by corporations not registered with the PCAOB?
(b) What does the second regression say about the audit charges paid by corporations audited by corporations registered with the PCAOB in contrast to corporations audited by corporations not registered with the PCAOB?
5. Irregular accruals may be both constructive or detrimental. Irregular accruals are calculated as a comparability of what the anticipated accruals are for an organization to the firm’s precise accruals. Constructive irregular accruals are revenue growing and detrimental irregular accruals are revenue reducing. The variable AbnAcc_W is the signed (constructive or detrimental) irregular accruals for every commentary.
(a) Create a knowledge body the place signed irregular accruals are solely constructive. With this new information body run the regression equation for each constructive and detrimental irregular accruals. In a desk report the coefficient estimates, the t values, and p values for the intercept and the impartial variables. Below this desk report the adjusted R-squared. Which impartial variables are statistically vital? Which impartial variables are related to extra constructive irregular accruals? Which impartial variables are related to much less constructive irregular accruals?
(b) Create a knowledge body the place signed irregular accruals are solely detrimental. With this new information body run the regression equation for each constructive and detrimental irregular accruals. In a desk report the coefficient estimates, the t values, and the p values for the intercept and the impartial variables. Below this desk report the adjusted R-squared. Which impartial variables are related to extra detrimental irregular accruals? Which impartial variables are related to much less detrimental irregular accruals?
6. How do the regression outcomes from Half 5 differ from the regression outcomes from Half 2?
6. Primarily based on the outcomes from the regressions in Half 5, how does contracting with an audit agency that is registered with the PCAOB impression audit high quality? Please be particular, don’t simply reply that it improves audit high quality, it doesn’t enhance audit high quality, or it makes audit high quality worse.
7. Primarily based on the Assessment you carried out in this assignment, if you have been in cost of recommending an audit agency to contract with for the firm you work for, would you suggest an audit agency registered with the PCAOB? What are the advantages of contracting with a PCAOB registered audit agency? What are the detriments of contracting with a PCAOB registered audit agency? Why did you make the advice you did?
