What is a fitted value for a multiple regression model and the
data that is used to create it? Select one.
-It is the difference between the actual value of the response
variable and the corresponding predicted value (regression error)
using the multiple regression model.
-It is a statistic that explains the relationship between
response and predictor variables.
-It is a statistic that is used to evaluate the significance of
the multiple regression model.
-It is the predicted value of...

1. A good predictive model is one that fits the data closely
whereas a good explanatory model is one that predicts new cases
accurately. A. True B. False
2. The specificity of a classifier is its ability to detect the
important class members correctly and sensitivity is its ability to
rule out C0 members correctly. A. True B. False

Consider a regression model of monthly
time series data where we model the price of petrol which is
dependent on the Crude Oil price and Exchange rate (against US$).
Data for the three variables were collected over a 50 month period.
Suppose the estimation results showed that the Durbin-Watson (DW)
test value d is 1.38. Perform the DW test for first order positive
autocorrelation of the error terms at the 5% level of
significance.
