Analyzing the data using r programming using random forest model.

/in /by

 Problem: The Texas A & M University Real Estate Center collects home listings data in Texas. One of the metrics is the number of months a home is listed until it sells (Texas A & M University, n.d.). A stagnant home listing is not beneficial to anyone in the process, typically impacting the individuals selling their dwellings the most. Opportunities to reduce the wait-time-to-sales for a particular home will reduce the potentially negative impact on the individuals selling their homes.

 Question: Using the data consolidated by Texas A & M University (n.d.), what predictors represent the majority of the explainable variance when predicting the number of months a property will remain in inventory considering the quantity of real estate sales, the monetary value of those sales, and the average sale price, the median sale price, and the quantity of properties in the inventory, the year, and the month in the data set? 

Objective: Use a random forest model as the analysis method to answer the research question. Additionally, consider how this research may help a realtor reduce the amount of time that their listings remain in their inventory when you discuss and present your findings.

Effects, Politics, and Regulatory Control of Tobacco Use

/in /by

Effects, Politics, and Regulatory Control of Tobacco Use
Tobacco use is the primary cause of  mortality in the United States today. Tobacco use is responsible for  cancer, chronic obstructive pulmonary disease (COPD), asthma, and heart  disease and has caused the deaths of nearly half a million people per  year. Tobacco control, prevention, and treatment are compelling and  urgent public health issues. The development of tobacco control laws  have been passed by a number of states.
Write a comprehensive overview of the  health effects, politics, and regulatory control of tobacco use control  efforts. Your paper should be based on the following points:

What are the factors (biological, environmental, economic, and  political) that contribute to tobacco addiction? What are the medical  consequences (morbidity and mortality) for tobacco users?
What is the public health impact (epidemiological and economic) of tobacco use and secondhand smoke exposure?
How do tobacco control regulations relate to positive and normative economics?
How do tobacco control regulations impact individual health care
What is the public health policy regarding tobacco control? What is  the role of the state and Federal Government in policy making?
What is the history of regulatory tobacco control? What is the  current state of tobacco control in the United States (states that have  passed tobacco control regulations)?
What is the evidence that tobacco control is effective?

Based on your understanding, create a 6- to  7-page Microsoft Word document that includes the answers to the above  questions. You need a minimum of five scholarly sources that should be  in APA format for both in-text citations and citations on the reference  page.
This assignment requires a title page, an abstract, an introduction, a body, a conclusion, and a reference page.

Part 3: Essay Question. Maximum length: 900 words, (weight 20 pts.) 

An enterprising group of entrepreneurs is starting a new data storage and retrieval business, SecureStore, Inc. For a fee, the new company will accept digitalized data (text and images, multimedia), and store it on hard drives until needed by the customer. Customer data will be transmitted to and from SecureStore over the Internet. SecureStore guarantees that the confidentiality and integrity of the data will be maintained.

SecureStore also envisions certain information assurance requirements for their internal operations. Company employees will need to exchange confidential email and will need a mechanism for verifying the integrity and originator of some email messages. Also, SecureStore intends a daily backup of all customer data to a remote facility via a leased line. They wish to do so as economically as possible, while ensuring the data’s confidentiality and integrity. 

Describe briefly how they would satisfy Secure Store’s requirements as stated above. How would a successful candidate respond? 

First, list the requirements derived from the above statements (note the highlighted words); list them and address each requirement. Keep in mind that this business will be operating in the real world, which means please pay attention to economics.
