Model Files:
For best results use the model installation file, it ensures that you have the proper drivers and settings. If you do not own a copy of Access the installation file will provide a runtime version for use with SELDM. The compiled version is available for advances Access users. The uncompiled Microsoft Access file is provided for future use by model developers.

Random Seed Files:
SeedMaker.exe was written to identify the random seeds used to generate uniform random variates in SELDM. It generates a set of random variates, calculates statistics, and outputs each random-seed pair with the maximum deviation from theoretical uniform random variate statistics (see appendix 1).
