k nearest neighbor classification 3

k-Nearest Neighbor Classification

The purpose of this assignment is to perform k-Nearest Neighbor classification, interpret the results, and analyze whether or not the information generated can be used to address a specific business problem.

For this assignment, you will use the “Adult Incomes” data set from the Topic Materials.

ABC Survey Company collects data via surveys that it then sells to marketing departments. Marketing departments typically do not like missing data. Since survey takers typically do not like to answer questions regarding their salary, the one question usually missing from the survey results is, “Is your annual salary $50,000 or more?”

You are the analyst who has been tasked with finding a way to impute (i.e., fill-in) the answer to the question, “Is your annual salary $50,000 or more?” This information can best be imputed based upon how individuals answer other survey questions related to their marital status, educational level, occupation, and familial relationship status. If this important question can be accurately imputed, then the worth of the survey data provided by ABC Survey Company increases dramatically.

Question 1: Using only “Marital_Status,” “Education,” “Occupation,” and “Relationship” variables, find the number of neighbors (k) that minimizes the error rate. Use a range of k between 3 and 10. Include the “k Selection Error Log” output when submitting the answer.

Question 2: Using the same variables and the k selected in Question 1, rerun the nearest neighbor model using the feature selection option in the IBM SPSS Modeler. What is the set of variables that minimize the error rate? Include the “Predictor Selection Error Log” output when submitting the answer.

Question 3: Using the value of k and the set of variables that minimizes the error rate, rerun the k-Nearest Neighbor model. What is the classification table? Include the pivot table output when submitting the answer.

Question 4: Consider the following individual: Marital_Status=Never-married, Education=Masters, Occupation=Sales, and Relationship=Not-in-family. Based on the k-Nearest Neighbor model from Question 3, how would this individual be classified? Provide the predicted income level (“>50K” or “<=50K”) and explain the process that you used to determine the income level. Include the table illustrating the data when submitting the answer.

Question 5: Describe the model building process you used to determine whether or not a particular survey taker earned an annual salary of $50,000 or more. Include discussion of the accuracy of the k-Nearest Neighbor model and how it can be used in practice to impute the answer to the question, “Is your annual salary $50,000 or more?”

Question 1:

From Ch. 19: Why is a behavioral review so relevant at this point in the planning process?  And… list and describe at least one of the five keys to a successful financial plan.

Student 1:

A behavioral review is relevant when completing the planning process because human behavior and its shortcomings play an important role in the success of the plan. What a statistically sound plan achieves can fail to align with one’s personal goals and objectives. Therefore, they may not follow the advice that contribute to its success. Moreover, humans are susceptible to behavioral flaws such as biases, bad memory, and lack of knowledge, all of which can make a plan fail. 

According to Altfest (2017), five keys to a successful financial plan are A specific statement indicating that the goals are attainable considering the household’s financials. The disclosure of crucial assumptions such as “salary growth, financial investment returns, cost increases, retirement age, and longevity”. A behavioral review. Possible alternative solutions. For example, when forecasts show a shortfall, there should be solutions ranked by preference to remedy it. A review process that confirms if the statement in the first step still applies. 

Reference:
Altfest, L. J. (2017). Personal financial planning. McGraw-Hill Education.

Question 2:

From Ch. 19: What are some of the reasons that a financial plan is important?  How would you communicate this to a skeptic? 

Student 2:

The reason why the Financial plan holds a significant importance: Increase in cash flow: Lessening the unwanted expenditures which will also part of effective management of income which may aid to increase the cash flow and can be utilized for better opportunities. Effective management of income: Financial planning aids towards effective management of income which includes one’s earnings and expenditures during a certain time period and the savings that could be done during this time. This depicts an effective management of income. By managing this routine regularly can be compared with past trend which may result in increasing the efficiency  of management. Increase in Capital: When the cash flow increases the capital also increases which is utilized for investment that aids to improve the entire financial stability.  Better standard of living: Increase in wealth helps to make one’s standard of living better as the cash inflow increases.  Managing uncertainty: Managing uncertainty means to manage the future and not being wealthy which depends on how much one is prepared for any uncertainties that can rely in the future. Such financial planning can aid to oneself to be prepared for the future. 

With the help of all these reasons one could communicate this to skeptic that financial planning is important for personal as well as business environment.
