Available for Windows 3.1, 95, 98 and NT, our users like WINKS because they can use it without having to relearn it every time. They like how it simplifies data entry, leads you through an analysis without a lot of complex options, and helps you interpret your results. See for yourself by getting a copy of WINKS today.

Here is a list of the kind of procedures WINKS BASIC Edition can perform:

• Descriptive statistics include: mean, standard deviation, variance, median, minimum, maximum, standard error of the mean, percentiles, Tukey 5 number summary, confidence intervals, and more. Descriptive graphics include a histogram with a normal curve fit, a box-and whiskers plot, cumulative normal and cumulative distribution graph.

• Graphs include: Histogram with bell curve fit, comparison charts including box-and-whiskers plot, mean chart, median chart, and standard error chart. Also available are a multiple group (XY) scatterplot, multiple correlation scatterplot, survival analysis plot, and more. First Impression charts give you a wide range of graph display options including 3D, tape, area, pie and more.

• T-tests and Analysis of Variance (ANOVA) features include independent group t-tests and analysis of variance (up to 20 groups), paired t-tests and repeated measures analysis of variance, single sample analysis of variance and Dunnett's test. You can perform most of these analyses from raw data or from summary information.

• Non-parametric analyses include Mann-Whitney, and Kruskal-Wallis analyses for independent groups. Friedman's test is provided for paired or repeated measures analysis. Cochran's Q test is provided for dichotomous data analysis.

• Frequency and Crosstabulation includes Goodness of fit test, Frequency distribution, McNemar's test, Chi-square, Fisher exact test (one and two-tailed), Yate's Chi-square, Phi and Cramer's V, Relative Risk, Odds Ratio.

• Regression and Correlation features include simple linear and multiple regression, correlation matrix, R-square and Adjusted R-square, Pearson's and Spearman's coefficient tests for significance, data plots and residual plots, point biserial correlation.

• Survival Analysis includes actuarial and Kaplan-Meier life tables and comparison of survival curves.

• Simulations and Demonstrations include a coin flip simulation, a confidence interval simulation and a central limit theorem demonstration.

• WINKS uses industry standard dBASE files, and can import Excel, ASCII, 123 and files from other programs, which makes getting your data into WINKS quick and easy.

• Print results or capture text and graphic output for inclusion in reports or other word processed documents.

• Repeat the last analysis type with one click.

WINKS Professional Edition

The WINKS PROFESSIONAL edition includes all BASIC features (listed above) plus:

• The Advanced Analysis of Variance (ANOVA) module includes two factor analysis of variance (balanced or unbalanced), paired and repeated measures analysis, and Analysis of Covariance. Analysis of Variance output includes a summary listing of the input data, ANOVA Table, multiple comparisons (Newman-Keuls, Tukey HSD, or Scheffé), graphical summary of multiple comparisons and interaction plots. ANCOVA output includes significance tests and graphical output showing line comparisons.

• The Time Series procedure includes data plotting, autocorrelations, partial autocorrelations, automated help in choosing an ARMA (Box-Jenkins type) model, estimating parameters, differencing and forecasting. The program allows you to formulate a model (it will help you select a model using the W-Statistic technique), estimate the parameters of the model and create a forecast using your model (using three forecasting techniques). The forecast can then be displayed and captured as numbers in a file.

• The Quality Control procedure allows you to create X-Bar Charts, R-Charts, S-Charts I-Charts and P-Charts. It will automatically calculate 3-sigma limits, or you can specify your own limits. Data replicates can be balanced or unbalanced. X-Bar Charts can be displayed on the same screen with an R-Chart or an S-Chart.

• The Pareto Chart procedure allows you to display Pareto charts, which are used to determine priorities for quality improvement. The by-group feature allows you to display charts by a grouping factor (i.e., day of week, operator).

• The Advanced Regression procedure includes the following features: Polynomial Regression allows you to fit up to a sextic regression. All Possible Regressions analysis allows you to examine a large number of regression models so you can choose the one that best fits the data. Stepwise Selection allows you to quickly consider a large number of possible variables. It uses both forward and backward selection procedures, and allows you to specify entry and elimination thresholds.

• Additional Professional features include the ability to Sort a database, plus the Multiple Comparisons procedure allows you to perform custom multiple comparison procedures using Newman-Keuls, Tukey HSD, Scheffe', or Dunnett's test on up to 20 groups.



Other general features of WINKS include:

• WINKS on-screen help contains more than 200K of information including step-by-step examples of most analysis types.
• Select often-used options with one click of an icon. Repeat your last analysis type with only one click -- even if you have ended WINKS and returned.
• WINKS contains a Journal that allows you to place portions of analysis results in a file collecting all of your important results in one place so you can print, save or import them into a word processor later.
• The WINKS data spreadsheet now allows you to enter a formula for a column, and it will remember the formula, and automatically recalculate entries as you enter or change numbers. Also, you can add and delete records or fields on the fly, and change field specifications (i.e. name, width, etc) directly from the spreadsheet. New temporary delete and undelete options make creating a subset database a breeze.
• For some analyses, you can now display text and graphic output on the same screen. Graphs are automatically resized to fit on whatever size you make your window.
• Copy analysis output (both graphic and text) in the Windows clipboard for easy transfer to other programs.
