Follow the analysis steps described in the Getting Started with SAS Enterprise Miner text, pp.23-44 to create a new analysis project. Make sure you enter Prior Probability information (p. 39) and Profit Matrix information (p. 40). Then follow pp. 45-60. Generate descriptive statistics (pp. 46-51), create exploratory plots (pp. 51-53), partition the raw data (pp. 54-55), explore missing values (pp. 55-58), and replace observations with unknown levels (pp. 58-60). 2. Turn in a printed word document with (i) a brief one-paragraph description of the project problem, (ii) a brief one-paragraph outline of your analysis including a screen shot of your final Diagram, (iii) screen shots of various analysis steps as listed below, and (iv) your answers to the questions listed below.

Unformatted text preview: 2. A Multiplot of DONOR_AGE by TARGET_B, as shown on p. 53. 3. A similar Multiplot of RECENT_RESPONSE_PROP by TARGET_B. 4. A histogram for URBANICITY and an interacting histogram of SES, as on p. 58. Questions: 1. Compare multiplots in screen#2 and screen#3. Does one input variable appear to be more associated with donations than the other? What would you recommend regarding a predictive model for TARGET_B as a result of this observation? 2. What are your comments on the way missing values for the variable URBANICITY are associated with missing values for the variable SES? What would you recommend regarding a predictive model for TARGET_B as a result of this observation? 3. In your own words, explain the meaning of prior probabilities, as entered into our data source, following the instructions on p. 39. 4. In your own words, explain the meaning of the profit matrix, as entered into our data source, following the instructions on p. 40....
