What might the problem be with this time series regression? @ The high value of the Durbin Watson indicates that autocorrelation is not likely to be a problem VIF -1 indicates that multicollinearity is likely the problem. The data observations on attendees are clearly mismeasured as suggested by the low adj. R2. The low value of the Durbin Watson Statistic indicates auto correlation is Ckely a problem e4 pts Question 7 If you know the values of a quantitative Y and five quantitative X's, then in an attempt to predict Y you can use if you have a linear model and if you do not.
