Order Regression Analysis Business Question
Career Interest: Owning a Business
Part 1 of this assignment gives you an opportunity to research articles within your field of interest (i.e., your major) that used Linear Regression as a tool in their study. The purpose is to let you see that this tool is frequently used when modeling data. You are writing a business-oriented brief of the article that focuses on the statistics, not a technical recitation of its contents or a business review of the company or product(s).
In Part 2 of this assignment, you can read your classmate’s posts and the articles they found, select one, and do some critical analysis on that same article (not your classmate’s original post).
Find an article preferably in your major or industry (posted in the last 5-6 years) that explicitly used Linear Regression (Excel, SAS, SPSS, or any other such tool) as part of its analysis.
The article should address a specific business problem and use Linear Regression to solve it.
A generic article does not qualify – nor does an article that explains, teaches, or provides examples of Linear Regression.
Provide the URL to the article as a citation (not to any file you downloaded; other people must be able to easily access your source to do Part 2).
Briefly explain the business purpose of the model and the type of regression used (simple, linear / non-linear, integer, categorical, etc.) in summary form. These should be descriptions, not the mathematical details (such as the specific constraint formulas).
For this assignment, your audience consists of business people, not analysts or mathematicians.
Your readers also understand what Linear Regression is – do not take any time to explain it.
Mention the technique used to develop the model if that is given in the article (forward, backward, etc.)
Explain how well the article supports their findings (the various dimensions of Goodness of Fit)
Describe the benefits the company / author gained as a result of using Linear Programming on this business problem.
Explain what you’ve learned from this article about Linear Regression that you can apply to your career – some insight, awareness, or benefit that you weren’t fully aware of prior to doing this research.
Consider the following outline for your submission
Goodness of Fit
Do not do these
Do not select an article that talks about, explains, teaches, or provides examples of Linear Regression. The article must USE linear regression on actual data in the analysis of a business problem. If you are uncertain whether your article is appropriate for this assignment, email me the link for an assessment well before the due date.
Do not try to duplicate the solution itself in Excel; that is not the purpose of this assignment.
Do not take time explaining what Linear Regression is; you can assume that your reader has that understanding.
Do not introduce yourself – work history, interests, years at UM, major, ….
Do not detail a company, products, or people – although that is interesting. Since this is a statistics course, focus your work on the application of Linear Regression to their business problem or opportunity.
Note that most articles do not present the entire model or all of the data; they merely discuss it in general terms. Therefore you must read the article closely to extract as much as possible. If the authors provide too little information about the technique, either try to find a different article or clearly mention this weakness in your post (such an omission is an ethical issue since readers cannot fully grasp or validate the claim being made).
Part 2(I will send you some students to comment on after you send part 1):
Read 3-5 posts AND read the corresponding article
Select one for your comments
Download and read the Five Obstacles faced in Linear Regression
Download Five Obstacles faced in Linear Regression
article for use in this part of the assignment.
Explain why you think the Linear Regression did or did not support the article’s findings using the following criterion:
Variables that were included or excluded
Validity of the technique that was used (i.e., was Linear Regression an appropriate analytical tool for what the article was trying to claim)
Discuss at least three of the points from the “Five Obstacles” document as they relate to the article you are reading for this post.
Do not do these
Do not comment about the author’s work on their post – comment about the article and the characteristics noted above
Do not repeat what the article is about or the business, product, or service being
