- KWIKSTAT
- --------
- 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.
- ##3
-
- 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 2.10
-
- Module Function
- ------ ---------------------------------------------------------
- DATA Create a database, enter and edit data (KS21DATA.EXE)
-
- UTIL Output reports, output ASCII text files, setup, and create
- or modify images (KS21UTIL.EXE)
-
- STAT Descriptive statistics (KS21STAT.EXE)
-
- AOV1 Comparitive statistics. T-tests, Analysis of Variance,
- and Non-Parametric tests (KS21AOV1.EXE)
-
- REG Simple and Multiple Linear Regression (KS21REG.EXE)
-
- CROS Crosstabulation, Frequencies, Goodness of fit, Pictograph
- and Pie Charts (KS21CROS)
- LIFE Survival analysis, Life tables (KS21LIFE.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 Pearson's and Spearman's Correlation coefficients, and 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.
