Three main categories of predictive modeling problems - Answer- 1. Descriptive - Focuses on what happened in the past and aims to "describe" or explain the observed trends by identifying the relationships between different variables 2. Predictive - Focuses on what will happen in the future and is concerned with making accurate predictions 3. Prescriptive - Uses a combination of optimization and simulation to investigate and quantify the impact of different prescribed actions in different sce...

SOWK 562 Exam Questions with Correct Answers Nominal (Discrete) Variables - Answer-(Categorical) Has two or more categories, but no intrinsic ordering to the categories. Examples: gender, race, hair color, ice cream flavors, citizenship, marital status A purely categorical variable is one that simply allows you to assign categories, but you cannot clearly order the variables. If the variable has a clear ordering, then that variable would be an ordinal variable. Ordinal Variables - A...
