Information about “STAT”
STAT is a program that analyzes, plots and displays
statistical data from internal data files or imported DBASE III and
LOTUS 1-2-3 files.
The data files created may have up to 800 records, 10 fields
(variables) per record, and 10 characters for the name of each
variable. They can be viewed, edited, sorted, manipulated, and
printed. The program can analyze the data and produce a number of
graphs, including histograms, scatter plots, line plots, multi-line
plots, X-Bar and R Charts, pareto charts and bar charts. STAT can also
calculate the mean, median, mode, range, standard deviation, standard
error of the mean, and more.

STAT.DOC
This program ( STAT.EXE ) is written and compiled using
Borland's Turbo Basic. It was written to answer a need
for the graphic representation of data for Statistical
Process Control Programs.
Menu selections are by either the cursor keys or the
space bar.
All graphic displays stay on the screen until the space
bar is hit to give you time to look or to print the graph.
This program presumes some level of understanding of
statistics and thus, is self explanatory.
When all else fails, read the screen!
TECHNICAL NOTES
1. Curve fitting
a. Least Squares of the forms :
Y = m * X + b (straight line)
Y = m1 * X + m2 * X^2 + b (one cusp)
Y = m1 * X + m2 * X^2 + m3 * X^3 + b (twp cusps)
b. Powers of the form Y = m * X^b
c. Exponential of the form Y = m * e^(bX)
d. Logarithmic of the form Y = m + b * Log (X)
e. Multiple Regression has a maximum of 25 independent
variables.
FILE SELECTION
1. Dbase III - This will accept III or III+ files. It will only
read numeric and date fields.
2. LOTUS 123 - You must first name the range in LOTUS using
the /Range/Name/Create function. It is assumed that the
top ROW of the named range are the field titles. You must
also format the whole range in decimal format. The decimal
format can be different for each field.
NOTE : This will not accept range inputs such as A1..E55.
3. STATPLOT - These files are created using this program.
You can save Dbase or Lotus files in this format after
they are read above. This is especially useful if you are
only using a small amount of a large LOTUS or Dbase file.
If you hit return, it will display the files in the current
directory. If you enter a drive letter followed be a colon (:)
or a path followed by back-slash (\),it will display the files
as designated.
The F9 function key will store the previous drive letter or path
so that you do not have to re-type the drive or path.
PITFALL
If you are changing color in a monochrome system and the screen
blanks, hit F1 or F3 until text appears. If you accidently
hit return and save the blank screen, get out of the program by
either Ctrl-Break <return><return> or soft boot. You then
have to erase the color file named COLOR.DAT.
