MPL
provides economists with extensive analysis tools and utilities to
examine models. |

|
| Easily
Remembered Vocabulary
|
The
Modeleasy+ MPL contains two powerful commands that are familiar to all
economists - ESTIMATE and SIMULATE.
ESTIMATE
allows the estimation of the coefficients of a model, and SIMULATE solves the model. Since the MPL
contains these two powerful commands, the user can immediately start analyzing a model
without having to learn an extensive vocabulary. |
|
|
|
Optional Keywords
|
Optional
keywords enable fine tuning and total control of the analysis.
The use of optional keywords with the
ESTIMATE and SIMULATE commands allow the user to control the details of the model's
analysis. For example, the use of the "GLS" keyword with the ESTIMATE command
causes the analysis of the model to be done by the GLS algorithm instead of the default
OLS algorithm. |
|
|
| Tools and
Utilities |
Supporting tools and
utilities enhance the power of the basic commands to perform more
advanced analysis of the model.
These tools can be used to set options to be applied to
all estimations, controlling both the algorithm used as well as the statistical tests done
to determine the quality of the estimation. There are also tools which control aspects of
the model simulation. Utility commands can be used to control the output
of the analysis for purposes of saving the results for inclusion in a report, for example. |

 |
| Syntax |
The analysis
of a model consists of executing one or more commands from the Model
Processing Language (MPL). The form of a command in the MPL is
typically:
analysis_operation
model_name [ option_list ]
where
"analysis_ operation" is the name of an MPL command,
such as ESTIMATE or SIMULATE, and "model_name" is the name of
the model being analyzed. There are usually additional command options
which may be specified as indicated by the "option_list". |
