ln Ht = α + β ln Yt + γ ln rt + ut
Suppose one wanted to use an LM test to test for first-order
autocorrelation.
Q1. What is the auxiliary equation?
Q2. How would you calculate the test statistic?
Q1

auxiliary equation is
= 
0 + 
1 ln Yt + 
2 ln rt + 
1 
2)
TS - nR^2
where R^2 comes for regression in auxiliary equation
