ISYE 6414 - Unit 1; Questions and Answers 100% Verified response (dependent) variables Answer-one particular variable that we are interested in understanding or modeling (y) predicting or explanatory (independent) variables Answer-a set of other variables that might be useful in predicting or modeling the response variable (x1, x2) What kind of variable is a response variable and why? Answer-random, because it varies with changes in the predictor/s along with other random changes

Regression analysis correct answers measures the impact of a set of variables on another variable. Largely concerned with ESTIMATING/predicting the population mean or average value of the dependent variable based on the known values of the explanatory variable There are two Variables X and Y, representing the same population. How does changing X effect Y e.g E(Y | Xi) = f (Xi) Regression analysis (simple) correct answers concerned with the study of the relation between the dependent an...
