Subject: Leverage values
I am currently working on an assignment which includes estimating an
error correction model for stock prices. While validating the model I am
using leverage values as described in:
Russell, Davidson & Mackinnon, James G.: Estimation and Inference in
Econometrics, Oxford University Press 1993. pp32-39.
When I save the leverage values from SPSS they are not equal to the ones
calculated using the method described in the book mentioned above.
Instead I am using the PROC GLM in SAS to calculate the leverage values.
I would like to know if anyone could explain how the leverage values in
SPSS are calculated (The SPSS help file does not help a lot).
