All Rights Reserved  \nExclamation-Triangle MESSAGE FROM AMBROSE Exclamation-Triangle  \nThis review sheet (a. k. a. a “cheat sheet”) follows the order of topics in the ACTEX Study Manual for Exam PA and provides a “helicopter” HELICOPTER view of the entire PA exam syllabus. As you know, the focus of PA is on conceptual understanding Brain and written communication COMMENT-DOTS. To write welland score high, there are quite a lot of things you have to memorize as part of your exam prep, and this cheat sheet collects, I believe, the most important items all in one place for your convenience. Although no substitute for a thorough study of the manual BOOK-READER, this cheat sheet should be a valuable aid to enhance retention and memorization. When I took PA in December 2019, I used a preliminary version of this cheat sheet and found it quite useful. (It was only 7 pages long back then!) Please feel free to refine it and put in additional facts and tips that you think are valuable.  \n} | ~ 􀁿 LAUGH-SQUINT Laugh-beam LAUGH Laugh GOOD LUCK LAUGH Laugh LAUGH-BEAM Laugh-Squint 􀁿 ~ | }  \n1 General Model Building Steps  \n1.1 Problem Definition  \n􀀏 Three main categories of predictive modeling problems:(More than one category can apply in a given business problem.)  \n\n| Category | Focus | Aim |\n| --- | --- | --- |\n| Descriptive | What happened in the past | To “describe” or explain observed trends by identifying relationships between variables |\n| Predictive | What will happen in the future | To make accurate“predictions” |\n| Prescriptive | The impacts of different “prescribed”decisions | To answer the “what if?” and “what is the best course of action”questions |\n\n􀀏 Characteristics of predictive modeling problems:  \nB (Issue) There is a clearly identified and defined business issue to be addressed.  \nB (Questions) The issue can be addressed with a few welldefined questions.
