6.4 Predicting Prices of Used Cars. The file ToyotaCorolla.csv contains data on used cars (Toyota Corolla) on sale during late s

ummer of 2004 in the Netherlands. It has 1436 records containing details on 38 attributes, including Price, Age, Kilometers, HP, and other specifications. The goal is to predict the price of a used Toyota Corolla based on its specifications. (The example in Section 6.3 is a subset of this dataset.) Split the data into training (50%), validation (30%), and test (20%) datasets. Run a multiple linear regression with the outcome variable Price and predictor variables Age_08_04, KM, Fuel_Type, HP, Automatic, Doors, Quarterly_ Tax, Mfr_Guarantee, Guarantee_Period, Airco, Automatic_airco, CD_Player, Powered_Windows, Sport_Model, and Tow_Bar. a. What appear to be the three or four most important car specifications for predicting the car’s price?

Answer:

Compare the predictions in terms of the predictors that were used, the magnitude of the difference between the two predictions, and the advantages and disadvantages of the two methods.

Our predictions for the two models were very simmilar. A difference of $32.78 (less than 1% of the total price of the car) is statistically insignificant in this case. Our binned model returned a whole number while the full model returned a more “accurate” price, but ultimately it is a wash. Both models had comparable accuracy, but the full regression seemed to be better trained. If we wanted to use the binned model I would suggest creating smaller bin ranges to prevent underfitting the model. However, when considering the the overall accuracy range and the car sale market both models would be

What are the differences between a policy, a standard, and a practice? What are the three types of security policies? Where woul
hjlf

Answer:

  • The difference between a policy, a standard and a practice is as follow:
  1. Policy: It can be defined as the written instructions that describe proper behavior.
  2. Standard: It can be defined as the detailed statement of what must be done to comply with policy.
  3. Practice: It can be defined as the examples of actions that would comply with policy.
  • The three types of security policies are:
  • Enterprise Information Sec. Policy (EISP) : High level policy that sets the strategic direction, scope, and tone for the organization's security efforts. Use: It is used to support the mission, vision and direction of the organization and sets the strategic direction, scope and tone for all security efforts
  • Issue Specific Sec. Policy (ISSP) : An organizational policy that provides detailed, targeted guidance to instruct all members of the organization in the use of a resource, such as one of its processes or technologies. Use: It is used to support routine operations and instructs employees on the proper use of these technologies and processes
  • System Specific Sec. Policy (SysSP): Organizational policies that often function as standards or procedures to be used wen configuring or maintaining systems. SysSPs can be separated into two general groups-managerial guidance and technical specifications- but may be written as a single unified document. Use: It is used as a standard when configuring or maintaining systems.
  • ISSP policy would be needed to guide the use of the web, email and use of personal use of office equipment.
