Anytime we have a univariate model, we will be missing lots of RHS variables that probably matter. This means: The covariance will be hard to interpret We might be better off using the correlation coefficient Our residuals will not be zero The regression model is of no value All of the above are false Question 13 True or False: If we believe in a linear relationship that means the benefits to years in school is about the same when someone increases their years in school from 2 to 3 years, and when someone increases their years in school from 17 to 18. True False 1 pts More information is needed Question 14 "Yi" is The predicted value of the LHS variable for observation i, the observed value of the LHS variable for observation i The observed value of the LHS variable for observation i, the predicted value of the LHS variable for observation i and "Yi hat" is O the sample value of the LHS variable for observation i, the population value of the LHS variable for observation i The observed value of the RHS variable for observation i, the predicted value of the RHS variable for observation i < Previous O The predicted value of the RHS variable for observation i, the observed value of the RHS variable for observation i AUG 1 pts Question 15 True or False: E(E)=0 True False Not saved Next > Submit Q Anytime we have a univariate model, we will be missing lots of RHS variables that probably matter.
