                ANNOUNCING THE RELEASE OF S-PLUS VERSION 2.3 
                  FOR UNIX WORKSTATIONS AND COMPUTE SERVERS 
============================================================================

Statistical Sciences, Inc. (STATSCI), based in Seattle, Washington, has just 
released Version 2.3 of S-PLUS for Unix Workstations and Compute Servers. 
S-PLUS is a powerful system and extensible interactive language used for 
graphical data analysis, statistics and mathematical computing. 

GENERAL DESCRIPTION OF S-PLUS Version 2.3  
=========================================
S-PLUS is a fully supported superset of New S. New S was developed by 
Becker, Chambers and Wilks at AT&T Bell Laboratories in an ongoing research 
effort that now spans a decade.  Complete access to Unix tools is available 
from within S-PLUS. S-PLUS provides over 500 functions which may be easily 
extended by defining new functions written in the S-PLUS language and/or 
by incorporating user-supplied Fortran or C programs. 

STATSCI's ENHANCEMENTS AND EXTENSIONS
=====================================

  WINDOW SYSTEM INTERFACES
  ------------------------
  S-PLUS provides enhanced window system interfaces for X11, SunView, 
  and Apollo's Display Manager. The S-PLUS plot windows provide a small 
  palette of mouse-driven selections including point and click for instant 
  laser printer output (PostScript and LaserJet printers), plot orientation, 
  text point size, color selection, and copy creation.

  HIGH INTERACTION GRAPHICS
  -------------------------
  High-interaction graphics are provided in the form of pairwise scatter 
  plots, 3-D point cloud rotation, marginal histograms and scrollable case 
  listings, all with linked brushing.

  COLOR IMAGING
  -------------
  A function is included for creating grey-scale or color image plots.

  CLASSICAL INFERENCE 
  --------------------
  S-PLUS contains a basic set of classical methods for estimation and testing. 
  These methods are available in an interactive and graphical display form 
  which makes S-PLUS widely useful for both teaching and research. The methods 
  contained in Version 2.3 include:  

    t-test (paired and unpaired     One-way ANOVA with and without covariate
         equal and unequal var)     Kruskal-Wallis test  
    Wilcoxon signed rank test       Generalized Cochran Q test  
    Binomial test for p             Mantel-Haenszel test for association  
    Chisquare test for r X s        Stuart-Maxwell test for association 
    Fisher's exact test for 2 X 2   t-test for zero correlation  
    McNemar's Test for symmetry     Kendall's Tau and test for zero correlation
    Bivariate normality test        Spearman's Rho and test for 
    Univariate normality test 		 zero correlation 

  Additionally, the binomial, hypergeometric and Wilcoxon distributions have 
  been added to the list of distributions represented in S-PLUS.    

  MODERN REGRESSION TECHNIQUES 
  ----------------------------
  Regression model linearization (ACE) 
  Additivity and Variance Stabilization for regression (AVAS) 
  Projection Pursuit Regression 
  Least Median of Squared Residuals (LMS) Regression
  Kernel Smoothers, Friedman and Stuetzle's "Super Smoother" 

  TIME SERIES
  -----------
  Univariate ARIMA models
  Multivariate AR models 
  Robust Fits for univariate AR models
  Complex Demodulation
  Spectral Analysis
  General specification of filters and smoothers
  Robust filters and smoothers

  ROBUST METHODS
  --------------
  Bisquare estimates of location and scale  
  LMS regression 
  Generalized M-estimates of AR parameters in time series 
  Robust estimates of location and scale in time series   
  Robust filters and smoothers for time series

  GENERALIZED LINEAR MODELS (GLIM)
  --------------------------------
  This is a general implementation of McCullagh and Nelder's 
  Generalized Linear Models including gaussian, binomial, poisson, 
  gamma, and inverse gaussian error structures and identity, log, 
  logit, probit, square root, inverse and loglog link functions.  
  Model fitting includes offset and model sequence specification.
 
  SURVIVAL ANALYSIS
  -----------------
  Survival Curves including Kaplan-Meier and Fleming-Harrington
  Cox Proportional Hazards Models 
  G-rho family of tests for differences between survival curves

  NEW "HELP" FILES
  ----------------
  Revised "help" files format with additional information and references, 
  a permuted index for all the functions, optional pagers for scrolling, 
  and optional pop-up help windows.
