ISYE 6414 (REGRESSION) MIDTERM EXAM |ACCURATE ANSWERS |VERIFIED What are the variables in regression? - ACCURATE ANSWER1. Response (dependent) variable - one particular variable that we are interested in understanding or modelling, such as sales of a particular product. 2. Predicting or Explanatory (independent) variable - set of other variables that we think might be useful in predicting or modelling the response variable (like the price of a product) Which regression variable is a Ran...
