Name the “three” Clustering algorithms within cluster analysis. All 3 should be listed (one in each row). 1)   2) 3)

A large, national grocery retailer tracks productivity and costs of its facilities closely. Data were obtained from a single distribution center for a one-year period. Each data point for each variable represents one week of activity. The variables included are the number of cases shipped (x1), the indirect costs of the total labor hours as a percentage (x2), a qualitative regressor called holiday that is coded 1 if the week has a holiday and 0 otherwise (x3), and the total labor hours (Y). Use the R output below to answer the following questions.  Interpret what the coefficient of -13.16602 for the continuous variable X2 means in predicting the response variable. Write a complete sentence.

Which of the following is a variable selection technique based on shrinking coefficients to zero?

What is the benefit of using interactive Data Visualization?

Which of the following is not a supervised learning algorithm?
