Discuss the importance of regular expressions in data analytics. Also, discuss the differences between the types of regular expressions.

Choose two types of regular expressions… For example, [brackets] (Matches the enclosed characters in any order anywhere in a string) and *wildcards (Matches the preceding character 0 or more times) and discuss the differences between the two.

Please be sure to include two or three differences for each. Include how they help manipulate data.

Reply Post

When replying to a classmate, offer your opinion on what they think is the importance of regular expressions and whether you agree or disagree, and why.

Discussion Length (word count): At least 250 words (not including direct quotes).

References: At least two peer-reviewed, scholarly journal references.

The following alternatives are available to fill a given need which are expected to have the expected salvage value at the end of their normal life of the system.

Attributes                                              Machine A          Machine B           Machine C

——————————                    —————-     —————–       —————–

Estimated First Cost                           (A) $20000      (B) $60000           (C) $120000

Life Cycle (years)                                 (A) 4                  (B) 4                       (C) 6

Annual Operating cost (estimate)      (A) $35000      (B) $10000           (C) $4000

Estimated interest rate                        (A) 10%             (B) 10%                 (C) 10%

1).  Analyze the sensitivity of the preferred plan due to error in estimating the interest rate.

2).   Perform a multi-parameter sensitivity analysis involving the two parameters, Annual cost and First cost.  Determine, under what conditions, each alternative should be selected.

NOTE: the values of parameters in this case study are all estimates. Therefore, the real values are higher or lower than those in the table. To answer the questions A and B, assume that we may have committed X % error in estimating the First Cost , y % in estimation the Annual operations cost, and  Z% in estimation the interest rate. Therefore, the real value of say, First cost for Machine a is 20000(1 ± X), or the annual operating cost for machine A is $35000(1 ± Y). We know from past experience that, maximum error of estimate (for each of the First Cost and Annual Operating cost) is limited to 50% ,  and for interest rate it is limited to 30% .

Case Study 2: Improving E-Mail Marketing ResponseDue Week 8 and worth 160 points

Read the following case study.

A company wishes to improve its e-mail marketing process, as measured by an increase in the response rate to e-mail advertisements. The company has decided to study the process by evaluating all combinations of two (2) options of the three (3) key factors: E-Mail Heading (Detailed, Generic); Email Open (No, Yes); and E-Mail Body (Text, HTML). Each of the combinations in the design was repeated on two (2) different occasions. The factors studied and the measured response rates are summarized in the following table. 

Write a two to three (2-3) page paper in which you:

  1. Use the data shown in the table to conduct a design of experiment (DOE) in order to test cause-and-effect relationships in business processes for the company.
  2. Determine the graphical display tool (e.g., Interaction Effects Chart, Scatter Chart, etc.) that you would use to present the results of the DOE that you conducted in Question 1. Provide a rationale for your response. 
  3. Recommend the main actions that the company could take in order to increase the response rate of its e-mail advertising. Provide a rationale for your response.
  4. Propose one (1) overall strategy for developing a process model for this company that will increase the response rate of its e-mail advertising and obtain effective business process. Provide a rationale for your response. 

Your assignment must follow these formatting requirements:

  • Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
  • Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length. 

The specific course learning outcomes associated with this assignment are:

  • Build regression models for improving business processes.
  • Design experiments to test cause-and-effect relationships in business processes.
  • Use technology and information resources to research issues in business process improvement.
  • Write clearly and concisely about business process improvement using proper writing mechanics.

Hint:Overview: The One Thing That Changes Everything

Trust may be something we take for granted until it is injured or destroyed. When that happens, it assumes a new importance. When you think of the people that are important in your life, these are most likely people you trust. We live in a time when we are frequently reminded that trust has to be earned and then reevaluated. Think of some of the public figures that had been trusted and then lost that trust. As you work on this assignment, start developing your trust meter, the instrument that guides you when evaluating trustworthiness.

This assignment is worth 15 points.
