Parsimony in statistical modeling is often discussed in terms of Occam’s razor in the formulation of hypotheses. Address the following:

• Discuss the issues of overfitting versus using parsimony and how this is particularly important in big data analysis.
• Is overfitting more of a problem in the generalized least squares model?
• Discuss some hierarchical methods that do not require the parsimony of generalized least squares model.
• Discuss these hierarchical methods, and provide links to any references that you find on the topic.

Be substantive and clear, and use scholarly examples to reinforce your ideas.

Write two sections of your case study as follows: Information Systems (IS)/Information Technology (IT) Applications Implementation Recommendations (for this paper section, you will comprehensively analyze the required and the potential IS/IT applications from Case Study Waypoint #3 and prioritize one required and one potential IS/IT application and further make implementation recommendations for the selected required and the potential IS/IT applications) and Information Systems (IS)/Information Technology (IT) Applications Implementation Strategy (in this paper section you will specifically outline your implementation strategy for the selected required IS/IT application (based upon a 3 to 12 month timeline) and the selected potential IS/IT application (based upon a 6 to 24 month timeline). You will further create a Gantt chart for both the required IS/IT application and the potential IS/IT application (and place them appropriately in your Appendix section). Smartsheet (Links to an external site.) provides a free online Gantt chart tool (signing up for a free account is required – no payment information is required), or you may be interested in using Microsoft Project (Links to an external site.). Please also feel free to utilize a Gantt chart tool of your choice.    

Please construct a Word document (times new roman 12-point font, double-spaced, 1-inch margins, APA 7th edition in-text citations and end references). Please add additional sources to your References page. When complete, upload your document (it must include all sections – so you will have a total of seven for this submission) to Canvas using the appropriate link (you can upload it as many times as you want up to the deadline noting that the last submission will be graded. All uploads will be checked against SimCheck (a plagiarism tool). The below SimCheck criteria will be used as one of the grading criteria for your waypoint.

 Excel Chapter 9 Mid-Level 2 – Pizza Sales 

Project Description:

You manage a chain of pizza restaurants in Augusta, Lewiston, and Portland, Maine. Each store manager created a workbook containing the quarterly sales for each type of sale (dine-in, carryout, and delivery). You want to create links to a summary workbook for the yearly totals.

The Summary sheet should contain   the same formatting as the other sheets.
 

  Select the range A1:B7 in the Lewiston worksheet. Group the Lewiston and   Summary worksheets. Fill formatting only across the grouped worksheets.

Ungroup the worksheets and   change the width of column B to 16 in the Summary worksheet.

You are ready to insert   functions with 3-D references in the Summary worksheet.
 

  In cell B4, insert a SUM function that calculates the total Dine-In sales for   the three cities.

Copy the formula in cell B4 and   use the Paste Formulas option in the range B5:B7 to preserve the formatting.

You are ready to display the   Contents worksheet and insert hyperlinks.
 

  • Insert a hyperlink in cell A3 that links to cell B7 in the Augusta sheet.   Include the ScreenTip text: Augusta total sales (no period).

  Protect the worksheet without a password and using the default settings.

Hide the Future worksheet.

Create a footer with your name   on the left side, the sheet name code in the center, and the file name code   on the right side of the five visible worksheets.

Mark the workbook as final.
 

  Note: Mark as Final is not available in Excel for Mac. Instead, use Always   Open Read-Only on the Review tab.

Save and close Exp19_Excel_Ch09_ML2_Pizza.xlsx. Exit   Excel. Submit the file as directed.

Assignment Objectives:  Analyze testing methods to find out vulnerabilities

Assignment Directions:  Suppose, you want to find out vulnerabilities in a system by simulating an external attacker trying to gain access to the system. But, you don’t want to invest too much time in it. Which testing method will you choose for this purpose?  In a word document, discuss the assigned topic in approximately ten sentences. 

Describe the requirements for patentability and what is considered non-obvious.

To simplify our explanations about magnetic disk access speeds, in this chapter, we use rotation speeds of 3,600 rpm and sustained data transfer rates on the order of one megabyte per second. However, current technology has pushed those numbers higher. Research current rotation speeds and data transfer rates for magnetic disks. Cite your sources, dates of the published research, and the type of computer (laptop, desktop, and so on) that uses the disk.

Research Paper

 This week, you have read about entrepreneurship in a global economy. For your written assignment this week, complete a case study of the organization you work for (use a hypothetical or “other” organization if more applicable) that will address the following prompts:

• Describe the organization’s environment, and evaluate its preparedness to go global, if not already, and it’s strategy for staying global if it is.
• Research other company’s strategy for going global and explain if this will or will not work for your company. 
• Make a recommendation for a global strategy in the organization, including a justification for your recommendations.

Submit your midterm research paper as a single document. Your paper should meet the following requirements:

• Be approximately four to six pages in length, not including the required cover page and reference page.
• Follow APA 7 guidelines. Your paper should include an introduction, a body with fully developed content, and a conclusion.
• Support your answers with the readings from the course and at least two scholarly journal articles to support your positions, claims, and observations, in addition to your textbook. The UC Library is a great place to find resources.
• Be clearly and well-written, concise, and logical, using excellent grammar and style techniques. You are being graded in part on the quality of your writing.

Discussion:

Networks have changed drastically over the last 30 years.  With the first introduction of the 56k modem, which was about 3 typewriter pages per second, to speeds well over 1Gbps these days, the ability to use networks globally, has changed the way we do business.  Using research, determine where networks will go in the next 5-10 years and how that might impact the global economy.

Please make your initial post and two response posts substantive. A substantive post will do at least two of the following:
