Note on missing value code usage in:

R. Carter Hill, William E. Griffiths and Guay C. Lim, Principles of Econometrics, Third Edition, Wiley, 2008.

The textbook data sets use an entry of   .   to indicate a missing value. SHAZAM will translate this to zero and so will incorrectly treat the missing value as a zero.

To recognize missing values in SHAZAM a suitable numeric missing value code must be used. The SHAZAM default missing value code is -99999. Alternatively, a missing value code can be set with the command:

      SET MISSVALU=

The command SET SKIPMISS will turn on automatic deletion of missing observations in estimation work.

The command SET NOWARNMISS will turn off the printing of warning messages about missing observations.

The following data set has been prepared with SHAZAM missing value codes:
