TYPE: Interactive elementary statistics package      DATE:11-AUG-79

            NAME: SAMSTAT  (Installed as ...SST)
         PURPOSE: SST is an interactive elementary statistics
		  package. It provides a statistics 'calculator'
		  to the lab experimentor. SST is menu and prompt
		  driven, and quit usable by the computer novice.
		  SST does not 'compete' with advanced analysis
		  packages such as BMDP/SAS.
CALLING/INVOKING: >SST invokes the system. 
 COMPONENT FILES: The source ditribution kit for this package is
		  maintained in UIC LB:[10,15].


_______________ INPUT ________________
     SWITCHES: System global logic is controlled by a single menu
		which inquires of the user which analysis he desires
		to perform. The appropriate subroutine is then
		invoked. A BP2 global common is used for control
		of system logic.

      GLOBALS: SST runs 'stand-alone', i.e., it cannot be called as
		a subroutine, although the various work subroutines
		could easily be modified to be called by BASIC+2
		programs.

        FILES: The user has control over the file names used as input
		and output. If an asterik is used in place of an input
		spec, the terminal is the input device. SST files are
		BP2 virtual arrays.


     TERMINAL: See SAMSTAT.DOC for user instructions. SST is set up
		for (24 line) by (80 col) screens. SST uses no explicit
		terminal control, and should run on any standard
		terminal.



______________ OUTPUT ________________
 SYSTEM STATE: No effect. If SST is aborted or the system crashes,
		temporary files will exist in the users UIC.

      GLOBALS: None.

        FILES: The user can optionally keep his data in a permanent
		output file. This is a BP2 virtual array. SST uses
		temporary files in the users UIC that it creates with
		a time-stamped filename.

     TERMINAL: See SAMSTAT.DOC.


_______________ LOGIC ________________
         PROCEDURE: See SAMSTAT.DOC.
   ROUTINES CALLED: DATAIN is the driver module. The following
		work subs exist:
		ESCRWM	-Elementary statistics.
		EDIT00	-Edit data array.
		TRANSF	-Transform data array.
		ELEMEN	-Output elementary statistics.
		CROSS0	-Cross tab.
		CORREL	-Correlation matrix.
		RANK0C	-Rank correlation.
		CHI0SQ	-Chi-squared test.
		T0TEST	-T-test.
		STEPWI	-Stepwise/multiple regression.
		HISTOG	-Histogram.
		ANALYS	-Anova (1-way and 2-way)
		PLOTER	-Plot driver.
		SCATTE	-Scatter plot.
		REGRES	-Linear regression.

		The sources for all of the above are contained in
		.BPR files.

   FLOW: Controlled by user.


___________ MAINTENANCE ______________
   SOURCE LANGUAGE: BPR, a preprocessor for Basic+2.

  STATUS/UIC/FILES: The distribution/maintainence kit is contained
		    in UIC LB:[10,15]. THIS IS A "PRE-RELEASE" KIT,
		    i.e., now that we have a system that works, we
		    we intend to go back and redesign the system.

 RUN SYNTAX / HELP: The package is fairly helpful. The file SAMSTAT.DOC
		    contains user documentation and run info.

    HOW TO COMPILE: This is a 2 step process since the BPR preproccesor
		    must translate the sorce files. The entire SST
		    package can be built using the command file
		    SSTGEN.CMD, i.e., @SSTGEN.

      HOW TO BUILD: As written, SSTGEN.CMD invokes the TKB file
		   SAMSTAT.CMD and SAMSTAT.ODL. These files do not
		   make use of a core-resident BASIC+2 library.

       PRIVELEGED?: No.

           HISTORY: This package is based on the DECUS distributed
		STAT-11 package, as modified by numerous people. The
		package was converted from interpretive BASIC running
		under RSTE/S to BASIC+2 running under RSX-11M by
		Bruce Montague, USAF/SAM/BRSO. The package was then
		'metamorphized'	module by module by John Penn,
		USAF/SAM/BRP, and much design and validation work
		performed by the personnel of USAF/SAM/BRA.
