KWIKSTAT 3.0 LATENEWS, Info not in the manual
Page 2-24 - the reference to figure 2.2 should be 2.4.
Page 4-12 - the second paragraph under "Performing the Analysis:
should read "enter 2" instead of "enter 1."
Page 4-25 - the end of the first paragraph under "Performing the
Analysis" should be "press B" instrad of "press A."
1. Loading KWIKSTAT in a subdirectory that had a previous version of
KWIKSTAT will not overwrite any of your DBF files. To save space on
disk, erase old Kwikstat programs - KS21*.EXE
2. Hercules graphics monitors are supported on all modules except the
Simulations. Use a Hercules/CGA Simulator such as SIMCGA or HGCIBM
(both shareware programs) to allow you to run the simulations module
on a Hercules monitor. If you use a simulator, specify a CGA
monitor in the setup routine.
3. IMPORT COMMA DELIMITED DATA INTO A DBF FILE. This is an option in
UTILITIES. The data to be imported can contain numbers and character
fields. Character fields must be enclosed in quotes "". An example
file on disk is EXCOMMA.DAT. The first few lines of this file are:
"A",12,22.3,25.3,28.2,30.6,5,"Text"
"A",11,22.8,27.5,33.3,35.8,5,"Text"
"B",12,22.8,30.0,32.8,31.0,4,"Text"
"A",12,18.5,26.0,29.0,27.9,5,"Text"
"B",9,19.5,25.0,25.3,26.6,5,"Text"
The import procedure looks at the first line of the file to determine how
many field will be created, and the types. For this file, there are 8
fields. The first and last are character fields. The import will name the
fields VAR1, VAR2 and so on. You can change these names in the "modify
database" option in the main DATA menu. The import will attempt to create
widths that will allow full storage of numbers and text. Everything after
that is automated. You should look at the file with the List option in the
DATA menu to verify that the imported data is correct.
4. When displaying some graphs in EGA or VGA mode, you can change colors
using the following keys
F1, F2, F3 - change display colors
F5 - go to black and white
F8,F9,F10 - change background in VGA mode (gradual changes)
KWIKSTAT supports printing of graphs in CGA mode on most printers, so that
is how they are normally displayed. To capture and/or print graphs in EGA
or VGA mode, you should use one of the many capture routines on the market
such as Frieze in PC-Paintbursh, HiJaak, Inset, Collage, Pizzaz, or others.
5. To create a new variable, use the transformation option. Set the new
variable equal to some dummy value such as 0, or to an expression such
as AGE/WT. You can edit (enter data into) the new variable using the
Edit option.
6. The detailed statistics now contains the standard deviation
calculated by dividing by n-1 (usually called the sample st. dev.) and
by dividing by n (usually called the population st. dev.)
