AUTO

The AUTO command estimates models with autoregressive errors or moving average errors.

In general, the format is:

  AUTO depvar indeps / options


The available options are:

Option Description
DLAG  Used with first-order models to indicate that the first independent variable is a lagged Dependent variable.
DN  Divide by N instead of N-K to get Variances.
DROP  Drops first observation in estimation.
GS  Uses a grid search to estimate rho.
MISS  Maximum likelihood estimates are adjusted for any missing observations that were deleted with SKIPIF commands.
ML  Maximum Likelihood Estimation
NOPITER  Suppresses the printing of the iterations.
PAGAN  Used with ORDER=1 or ORDER=2 to estimate the model using Pagan's 1974 procedure.
CONV=  Sets a convergence criterion when the Cochrane-Orcutt by procedure is being used.
GAP=  Used when the missing observations were included in the data.
ITER=  Used when doing an iterative Cochrane-Orcutt procedure to control the number of iterations.
NMISS=  Used with the GAP= option to indicate how many observations are missing from the data.
NUMARMA=  Used with PAGAN option to specify the number of AR or MA coefficients to be estimated.
ORDER=n  Used to estimate models with second or higher order autocorrelation.
ORDER=-n  Model will be estimated using a moving-average error model instead of an autoregressive error model. DLAG, DROP, GAP, GS, MISS, ML, RESTRICT, RHO and SRHO may not be used.
RHO=  Specifies rho desired by user.
SRHO=  Specifies rho for second order.

Other available options are:
ANOVA, DUMP, GF, LININV, LINLOG, LIST, LOGINV, LOGLIN, LOGLOG, MAX, NOCONSTANT, PCOR, PCOV, RESTRICT, RSTAT, BEG=, END=, COEF=, COV=, PREDICT=, RESID=, STDERR= and TRATIO= as defined for OLS.

The available temporary variables on the AUTO command are:
$DF, $DW, $ERR, $K, $LLF, $N, $R2, $R2OP, $RAW, $RHO, $SIG2, $SSE, $SSR, $SST, $ZDF, ZSSR, $ZSST.
