nlmdl is a C++ implementation of the statistical methods in A. Ronald 
Gallant, "Nonlinear Statistical Models," New York: John Wiley and Sons, 
1987, ISBN 0-471-80260-3, using a matrix class realmat that is distributed 
with it.  The header files nlmdl.h and realmat.h describe the use of the 
program and matrix class, respectively.
