You can use the OUTEST= option in the ESTIMATE statement to store the model parameters and the related estimation details. This data set contains the following columns:
the BY variables
COMPONENT, a character variable containing the name of the component corresponding to the parameter being described
PARAMETER, a character variable containing the parameter name
TYPE, a character variable indicating whether the parameter value was fixed by the user or estimated
_STATUS_, a character variable indicating whether the parameter estimation process converged or failed or there was an error of some other kind
ESTIMATE, a numerical variable containing the parameter estimate
STD, a numerical variable containing the standard error of the parameter estimate. This has a missing value if the parameter value is fixed.
TVALUE, a numerical variable containing the t-statistic. This has a missing value if the parameter value is fixed.
PVALUE, a numerical variable containing the p-value. This has a missing value if the parameter value is fixed.
