GAUSS Mathematical and Statistical System 8.0

GAUSS 8.0 includes a number of new features and enhancements which dramatically increase your ability to optimize your programs.

Features and Enhancements
Sparse matrix data type
GAUSS Profiler
Sparse matrix and structure support in GAUSS Data Archives
Several new GDA functions
New functions for testing hypotheses about constrained models
New standard deviation functions
Support for adding structures to libraries
Support for extra library paths
Improved file/line number handling in error returns
Sparse Matrix Data Type

The new sparse matrix data type allows for the use of sparse matrices in many matrix functions and operators. New functions have also been added for creating and manipulating sparse matrices.

GAUSS Profiler

The GAUSS Profiler is a significant new feature that will allow you to optimize your programs rapidly. The GAUSS Profiler will analyze your GAUSS programs and produce a report of how much time is spent on each line and in each called procedure. This gives you the information needed to optimize your programs.

Hypotheses Testing Functions

Two new functions in GAUSS implement a new method for testing hypotheses in models with constraints on parameters. Current methods for computing standard errors for constrained parameters are only approximate; these new functions are the only correct method for computing these standard errors, and they are only available in GAUSS at this time.

Additional New Features
Sparse matrix and structure support in GAUSS Data Archives, including support in existing GDA functions as well as adding new functions
Support added for reading from and writing to GDA's created on other platforms, providing an easy and efficient way to transfer data between platforms
New GDA functions for saying all or a subset of the variables in a workspace to a GDA and for loading all of the variables in a GDA into a workspace
New standard deviation functions
Support for adding global structures to libraries
Support for extra library paths added
Improved file/line number handling in error returns
Other new functions added
