Congratulations, you have passed the first test and received the nls2
The nls2 distribution is very large, and can not be distributed by
e-mail. In order to obtain robeth you will need either FTP, gopher, or WWW
access to StatLib. (To get started with FTP, gopher, or WWW send the
one line message
to firstname.lastname@example.org). The nls2 distribution is in the directory
S/Nls. The nls2 file is
nls.tar.Z and it is compressed tar file
of 1.2 Mbytes
When using FTP remember to use BINARY mode (these are compressed files)
Here is a short description of nls2.
This system is a set of SPlus functions and programs
to estimate the parameters of a non-linear
regression model over a given set of observations.
The regression function can be defined explicitly as a function of
independent variables and of unknown parameters or it can
be defined as the solution of a system of differential equations.
Heteroscedasticity of errors can be taken into account by modelling
the variance function.
The model should be described in an operating-system file.
See the Reference Manual in the LaTeX file "doc/Manual.tex" for
additional statistical information.
Comments or suggestions may be sent to Bouvier (email@example.com)
but help to people who have problems is not assured.
The installation has been tested on SunOs 4.1 and SolarisOS using SPlus 3.1.
C and Fortran compilators should be available.
This directory contains the following files:
ReadMe - you're looking at it.
INSTALL - a shell-script to install the system
TEST - a shell-script to test the installation
Makefile - a makefile used by INSTALL
Copyright - the copyright
Summary - a short summary to put in the S index.
CREATE.distrib -a shell-script to create a directory to be sent to others installators
from an installed version (i.e where the object-files and .Data directories
CREATE.solaris -a shell-script to transform a Sun-OS version into a Solaris-OS one
(or any site where neither the OS-command "ranlib" nor the S-command "dyn.load2"
and the directories:
doc - the documentation files:
"Manual.tex, epres.tex, enota.tex, bib1.bib" are the LaTeX source-files
of the Reference Manual.
"nls2.l" is the Unix man (nroff source file) that SHOULD BE
MODIFIED by the installator to mention the pathname of the
newfun - the source-files of the S-functions
helps - the helps files
src - the source-files of the programs called by the functions
lib - a Makefile for generating the object-files corresponding to "src"
and, after installation, these object-files.
analder, crpsi, crinv, nl, lsoda: the packages used by nls2. These are:
the formal analysor-derivator of the model description,
the formal analysor-derivator of functions description,
the formal analysor-derivator of inverse model description,
the estimation package and the integrator system.
In each of these directories, you could find the files
"Makefile", "ReadMe" and the directories "src" and possibly
In each of these directories, the shell-script "INSTALL" will
create a directory named "lib" containing the object-files
In the "nl" directory, the file "FileMess" contains the text
of the messages issued by this package.
examples - the examples. Each one is in a sub-directory (see examples/ReadMe).
tests - the examples after execution. The "tests" directory is
used by the shell-script TEST to verify the installation
and can be destroyed afterwards.
- Before installation, on a Solaris-OS site (or any site where neither the OS-command "ranlib"
nor the S-command "dyn.load2" is available), use the shell-script CREATE.solaris:
see the included comments.
- Use the shell-script INSTALL for installation: see the included comments.
