HOW TO ENTER DATA

Data may be entered from the keyboard, or from an ASCII text file. Data 
already stored in a dBASE III file may also be used. 

                        ENTERING DATA FROM THE KEYBOARD

STEP 1:Create the structure of your database by selecting the "CREATE"
option in the DATA module. Define names for each variable, maximum width of 
the field, and type of variable. (Character or Numeric).

STEP 2:Answer "Y" to "Enter data now?(Y/N)"

STEP 3:The "EDIT" option may be used to make corrections.

##2
                     ENTERING DATA FROM AN ASCII TEXT FILE

Create a database structure using the CREATE option. This structure should 
match the columns of data in the data file. For example, your data is in a 
file named "MYDATA.TXT". A database structure could be created using the 
following format: 

Field Type  Width  Dec

NAME    C    10
AGE     N     2     0
BDATE   D     8
 ^      ^     ^     ^                                                          
 │      │     │     └─────────────Number of decimals in numeric data           
 │      │     └───────────────────Columns where data is found                  
 │      └─────────────────────────Data type
 └────────────────────────────────Variable (field) name                        
                                                                               
This means NAME is in columns 1-10, AGE in 11-12 and BDATE in 13-21.
NOTICE:The format MUST be inclusive of all columns. DO NOT SKIP COLUMNS when
specifying where data is located.

                      ENTERING DATA FROM A DBASE III FILE

KWIKSTAT reads data directly from dBASE III files. In each module, you may 
specify which dBASE file to use. The module will display all ".DBF" files in 
the default path. However, you may also call files from other directories
using drive and path names. For example, if you wish to access a file in the 
subdirectory named DB3, specify the name of the database "MYBASE" as 

\DB3\MYBASE      or C:\DB3\MYBASE if it is on disk drive "C:"

##4

                     SET UP DEFAULT DISK PATH OR DISK DRIVE

In the UTIL module, select the option to set up the default disk drive or 
path. This is not needed if data and program are in the same subdirectory. 

If the data is stored in another drive, such as drive B, specify the default
drive, "B:".

If the data is stored in another subdirectory, such as "MYDIR", specify this
as "\MYDIR\" or "C:\MYDIR\"

The path will be added to the beginning of filenames used in the program.

##5 HOW KWIKSTAT WORKS
             Here are the basic divisions of KWIKSTAT Version 2.00

Module      Function
------      ---------------------------------------------------------
DATA        Create a database, enter and edit data (KW20DATA.EXE)

UTIL        Output reports, output ASCII text files, setup, and create
            or modify images  (KW20UTIL.EXE)

STAT        Descriptive statistics (KS20STAT.EXE)

AOV1        Comparitive statistics. T-tests, Analysis of Variance,
            and Non-Parametric tests (KS20AOV1.EXE)

REG         Simple and Multiple Linear Regression (KS20REG.EXE)

CROS        Crosstabulation, Frequencies, Goodness of fit, Pictograph
            and Pie Charts (KS20CROS)
LIFE        Survival analysis, Life tables (KS20LIFE.EXE)
------      ---------------------------------------------------------  
##6
                          KWIKSTAT UTILITY - REPORTS

KWIKSTAT allows you to create and output data to the file or printer in the
UTIL Module.

o  Output a listing of the data in the dataset (or a selected subset of the 
database). In this procedure you may specify column headings, inclusion of
record number on the report, width and length of a page, and report title. 
A selection procedure is ued to output a report on a subset of the database.

o Output the data into a standard ASCII TEXT file. This is useful for
transferring the data to other programs. Along with the output of data, you 
may also output a "format" file, which describes the contents of the text 
file.

##7

                             DESCRIPTIVE STATISTICS

In the STAT module, you are allowed to examine summary statistics of the data
in the database. Graphic presentations available in this module:

o HISTOGRAM    : examine the distribution of a continuous variable
o SCATTERPLOT  : examine the relationship between two variables
o TIME-SERIES  : examine pattern of a single variable across time
o BOX PLOT     : used in detailed statistic on a singe variable
##8
                              T-TESTS AND ANOVA'S

FOR INDEPENDENT GROUPS OR SINGLE GROUP
--------------------------------------
o Two groups:Student's t-test

o 3 to 10 groups: One way analysis of variance, Newman-Keuls multiple
  comparisons performed at the 0.05 significance level.

o t-test and ANOVA from summary data

o Single sample t-test

FOR PAIRED OR REPEATED MEASURES
-------------------------------
o Two time periods or two paired observations:Students t-test for paired
  observations.

o 3 to 10 repeated measures: Repeated Measures Analysis of Variance, with 
  Newman-Keuls multiple comparisons.
##9 Linear regression

                               LINEAR REGRESSION

o Comparing paired observations, simple or multiple linear models

o The equation of the line is calculated

o Correlation coefficient, R²

o Test's for significance of parameters

o Scatterplot, graphical examination of residuals

o Multiple regression on up to 10 independent variables

##10

                               SURVIVAL ANALYSIS

The Kwikstat LIFE program expects data to be in the following format:

1. A time variable that measures the length of time from the beginning of the 
measured event until failure or end of measurment.

2. A censor value (0 or 1) where 1 means that the subject ended in failure 
(death), and 0 means that the subject is still being followed (alive).

3. Optionally, there may be a grouping variable.  If a grouping variable is
chosen, a statistical test for the comparison of the survival curves will be 
calculated.

A life table and survival curve will be generated for each group.
