ISYE 6414 REGRESSION MIDTERM 1 REAL EXAM 2023/2024 What are the variables in regression? -CORRECT 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 Random variabl...

ISyE 6402 Midterm Prep (2023/2024) Already Passed Getting a 3 variable VAR model from summary(model) output of a VAR(1) model first matrix: first row are coefficients for Xt1, second row are coefficients for Xt2, etc... second matrix is Xt-1, i b/c this is a VAR(1) model last matrix are the constants eta_t is covariance matrix, direct copy (c) Based on the fitted model, is there contemporaneous cross-correlation? Is there lagged cross-correlation? Is there lagged auto-correlation? Explain. con...
