• QUESTION : (Solved) : Use Questions 1 4 Reality Patients Needing Organ Transplant Organs Available National Wait Q31281311 . . .

Use for Questions 1 to 4 In reality, there are more patients needing an organ transplant than there are organs available. Because of this, a national waiting list is used to orderly assign available organs to patients. Suppose a researcher records monthly the number of patients that die on the waiting list, are transplanted, or are censored (due to the end of the study). Assume that the censoring occurs exactly at the end of each month. Let D be the month that the subject would have died on the waiting list without a transplant. Let T be the month the patient would have been transplanted had they remained on the waiting list. Finally, let C be the end of the month a random patient is censored from the study. The challenge is that once a patient is censored or is transplanted we do not know the time at which they would have died on the waiting list. That is, we only get to observe min(D.T.C) and the type of event (death, transplantation, censoring). Assume throughout that P(T = tlT > t-land D > t _ 1 and C > t-1-P(T = t|T > t-land D > t-1) and P(D = tlT > t _ 1 and D > t _ 1 and C > t-1)-P(D = t[T > t-1and D > t-1) Suppose that the data were collected over the first 6 months of being on the waiting list for 1,000 patients. So Dt the number of people that die off the waiting list, · Tt = the number transplanted during a particular month, . Cr the number of people censored at the end of the month, and ne the number of people at risk during the start of the interval.

• QUESTION : (Solved) : Use R Programming 60 Points File Socialnetworkadscsv Dataset Effective Ads Social Media D Q26379642 . . .

Use R programming

[60 points]

The file “Social_Network_Ads.csv” is a dataset about howeffective the ads on social media are. The data has three variables(Gender, Age, and Estimated Salary) and one response variable(Purchased). This response variable has two value 0 (no purchased)and 1 (purchased successfully) (Let’s consider 0 and 1 as factor,not number).

A)Split the data into training (75% of the data) and testing set(25% of data left)

B)Build a decision tree model for the training set. Predict theresponse value for the testing set. Report your confusion matrixfor the prediction and plot the decision tree.

C)Build a random forest model for the training set. Predict theresponse value for the testing set. Report your confusion matrixfor the prediction. Compare the result with part b? Is there anydifference? Explain?
