SHAZAM Command Reference

Command	Description
ARIMA (Autoregressive Integrated Moving Average Models)	The ARIMA command estimates Univariate ARIMA models. There are 3 forms of the command: IDENTIFICATION, ESTIMATION, and FORECASTING. The specified options determine which form of the ARIMA command is in effect.

IF1	Equivalent to a SAMPLE 1 1 and an IF command
INDEX (Price Indexes)	Calculates price and quantity indexes
INST	The INST command is identical to the 2SLS command.
INTEG	The INTEG command will perform numeric univariate integration on an equation.
LAMBDA (Lambda Restrictions)	The LAMBDA restriction command is used with the BOX command to impose restrictions on LAMBDA on individual variables. The RESTRICT option on the BOX command must be specified if the LAMBDA command is used. The END command must follow the restrictions
LOGIT (Logit Models)	The LOGIT command does Logit regressions. The format and options are the same as those for PROBIT.
