logistic regression: using sas
Problem 1 Churn analysisGiven the large number of competitors, cell phone carriers are very interested in analyzing and predicting customer retention and churn. The primary goal of churn analysis is to identify those customers that are most likely to discontinue using your service or product. The dataset churn_train.csv contains information about a random sample of customers of a cell phone company.The company is interested in a churn predictive model that identifies the most important predictors affecting probability of switching to a different mobile phone company (churn = 1). Answer the following questions:Create two boxplots to analyze the observed values of age and PCT_CHNG_BILL_AMT by churn value. Analyze the boxplots and discuss how customer age and changes in bill amount affect churn probabilities. Include the boxplots.Using a selection method, fit the final logistic regression model to predict the churn probability using the data in the dataset (Churn is the response variable and the remaining variables are the independent x-variables). Include the SAS output. Write down the expression of the fitted model. Analyze the final logistic regression model and discuss the effect of each variable on the churn probability. Using SAS, compute the predicted churn probability and the confidence interval for a male customer who is 43 years old, and has the following information LAST_PRICE_PLAN_CHNG_DAY_CNT=0, TOT_ACTV_SRV_CN=4, PCT_CHNG_IB_SMS_CNT= 1.04, PCT_CHNG_BILL_AMT= 1.19, and COMPLAINT =1. Include the output, interpret and explain the 3 values you obtained.Copy and paste your FULL SAS code into the word document along with your answers.

Rational Functions ApplyDetermine whether the statement is true or false. Justify your answer.1. A rational function must have at least one vertical asymptote.Use a graphing utility to graph the function. Explain why there is no vertical asymptote when a superficial examination of the function might indicate that there should be one.2. g(x) = Use a graphing utility such as Desmos. Graph this equation: y = (x + 5) / (x^2 + 1). Why is there no vertical asymptote? Use RATIONAL FUNCTIONS please.Please upload the original file as well as a PDF export.Everything you need to know is above.

Problem 1 You wish to determine the GPA of students at your school. Describe whatprocess you would go through to collect a sample if you use a systematic sample. Problem 2 The number of deaths in the US due to carbon monoxide (CO) poisoning fromgenerators from the years 1999 to 2011 are in table #1 (Hinatov, 2012). Create a bar chart and pie chart of this data. State any findings you see from the graph.

Create a frequency distribution, relativefrequency distribution, and cumulative frequency distribution using 8 classes. b.) Create a histogram for the data in table #2.Describe the shape and any findings you can from the graph. c.) Create an ogive for the data in table #2. Describe any findings you can from the graph.

The data for 24 randomly selected countries forthe year 2011 are in table #3. Create a scatter plot of the data and state if thereappears to be a relationship between life expectancy and the number of births perwoman. Table #3: Data of Life Expectancy versus Fertility Rate Life Expectancy Fertility Rate Life Expectancy Fertility Rate 77.2 1.7 72.3 3.9 55.4 5.8 76.0 1.5 69.9 2.2 66.0 4.2 76.4 2.1 55.9 5.2 75.0 1.8 54.4 6.8 78.2 2.0 62.9 4.7 73.0 2.6 78.3 2.1 70.8 2.8 72.1 2.9 82.6 1.4 80.7 1.4 68.9 2.6 74.2 2.5 81.0 1.5 73.3 1.5 54.2 6.9 67.1 2.1 Problem 5 Cholesterol levels were collected from patients two days after they had a heartattack (Ryan, Joiner & Ryan, Jr, 1985) and are in table #4.
