StatTools gives the industry-standard data analysis tool— Microsoft Excel—a new, powerful statistics toolset! StatTools is a Microsoft Excel statistics add-in, so you analyze data in Excel and work in the familiar Microsoft Office environment. StatTools brings you the best of two worlds: Microsoft Office ease-of-use, and robust statistical power. Plus, StatTools is developed by Palisade Corporation, the world leader in analytical solutions that add-in to Microsoft Excel.
Excel Ease of Use
StatTools is a true add-in to Microsoft Excel, integrating completely with your spreadsheet. Browse, define, analyze � while never leaving Excel. StatTools replaces Excel�s built-in statistics functions with its own calculations. The accuracy of Excel�s built-in statistics calculations has often been questioned, so StatTools doesn�t use them. All StatTools functions are true Excel functions, and behave exactly as native Excel functions do. StatTools calculations are optimized through the use of C++ .DLLs, not macro calculations.
How StatTools Works
StatTools covers the most commonly used statistical procedures, and offers unprecedented capabilities for adding new, custom analyses. Over 30 wide-ranging statistical procedures plus 9 built-in data utilities include forecasts, descriptive statistics, normality tests, group comparisons, correlation, regression analysis, quality control, nonparametric tests, and more.
StatTools features live, "hot-linked" statistics calculations. Change a value in your dataset and your statistics report automatically updates. There is no need to manually re-run your analyses.
The Best in Data Management
Excel Developer Kit (XDK)
StatTools includes a complete, object-oriented, programming interface—the Excel Developer Kit (XDK). Custom statistical procedures may be added using Excel's built-in VBA programming language. Utilize StatTools's built-in data management, charting and reporting tools.
Statistical Inference: This group performs the most common statistical inference procedures of confidence intervals and hypothesis tests.
Forecasting: StatTools gives you several methods for forecasting a time series variable. You can also deseasonalize the data first, using the ratio-to-moving-averages method and a multiplicative seasonality model. Then use a forecasting method to forecast your deseasonalized data, and finally “reseasonalize” the forecasts to return to original units.
The outputs include a set of new columns to show the various calculations (for example, the smoothed levels and trends for Holt’s method, the seasonal factors from the ratio-to-moving-averages method, and so on), the forecasts, and the forecast errors. Summary measures such as MAE, RMSE and MAPE are also included for tracking the fit of the model to the observed data. Finally, several time series plots are available, including a plot of the original series, a plot of the series with forecasts superimposed, and a plot of the forecast errors. In cases using deseasonalized data, these plots are available for the original and deseasonalized series.
Classification Analysis: StatTools provides both discriminant analysis and logistic regression. Discriminant analysis predicts which of several groups a variable will fall in, and logistic regression is a nonlinear type of regression analysis where the response variable is 0 or 1 for “failure” or “success.” You can then estimate the probability of success.
Data Management: This group allows you to manipulate your data set in various ways, either by rearranging the data or by creating new variables. These operations are typically performed before running a statistical analysis.
Summary Analyses: This group allows you to calculate several numerical summary measures for single variables or pairs of variables.
Tests for Normality: Because so many statistical procedures assume that a set of data are normally distributed, it is useful to have methods for checking this assumption. StatTools provides three commonly used checks: Chi-square, Lilliefors, and Q-Q plot.
Regression Analysis: For each of these analyses, the following outputs are given: summary measures of each regression equation run, an ANOVA table for each regression, and a table of estimated regression coefficients and other statistics. In addition, StatTools gives you the option of creating two new variables: the fitted values and residuals. Plus, you can create a number of diagnostic scatterplots.
Quality Control Charts: This set of procedures produces control charts that allow you to see whether a process is in statistical control. Each of the procedures takes time series data and plots them in a control chart. This allows you to see whether the data stay within the control limits on the chart. You can also tell if other nonrandom behavior is present, such as long runs above or below the centerline. Each of these procedures provides the option of using all the data or only part of the data for constructing the chart. Furthermore, each lets you base the control limits on the given data or on limits from previous data.
Nonparametric Tests (Industrial edition only): Nonparametric tests are statistical procedures which can be used to make successful inferences when there is little available data. They are more robust than many of the widely known parametric hypothesis tests. Nonparametric tests do not always need the parametric assumptions—such as normality—or generalized assumptions regarding the underlying distribution. In most cases, the nonparametric tests are much easier to apply and provide clearer interpretation than traditional parametric tests.

Two Editions to Meet Your Needs
StatTools comes in Professional and Industrial editions. The Industrial edition of StatTools adds the following features:
Expanded data sets - Define variables that span multiple worksheets. The Professional edition allows 10,000 data points for a single variable.
Nonparametric tests - Nonparametric tests are statistical procedures which can be used to make successful inferences when there is little available data.
StatTools Features & Benefits
Southern California Edison
Part of the DecisionTools Suite
StatTools is available by itself or as part of the DecisionTools Suite, Palisade’s complete risk and decision analysis toolkit. The DecisionTools Suite includes @RISK for risk analysis with Monte Carlo simulation, NeuralTools for predictions using neural networks, Evolver for optimization, PrecisionTree for decision trees, and more. StatTools is fully compatible with all DecisionTools programs and can be combined with them for greater insight and analysis. For example:
Combine StatTools with @RISK to assess confidence intervals on simulation results. You can also apply @RISK functions to StatTools time-series forecast results to simulate possible outcomes with more precision than the times-series analysis alone. Run RISKOptimizer on your model using the same @RISK functions in order to find the best combination of factors to maximize your forecasted profits.

Save Over 50% When You Buy the Suite
The DecisionTools Suite costs less than buying just two component products separately. In fact, you save over 50% versus buying all components individually. The best analyses at a great price–with the DecisionTools Suite.

StatTools calculations are performed 100% within Excel,supported by Palisade sampling and statistics proven inover twenty years of use. Palisade does not attempt to rewrite Excel in an external recalculator to gain speed. Asingle recalculation from an unsupported or poorly reproduced macro or function can dramatically change your results. Where will it occur, and when? Get accurate results using StatTools!
Licensing and Training
StatTools is available through a variety of licensing options, including corporate, network, and academic licenses. Training, consulting, and books can be bundled with your software to ensure you and your staff get the most out of your investment.
Included with your StatTools purchase, this book is written to help you get the most out of StatTools in a practical, straightforward manner. Much more than a software manual, this book shows you how to apply statistics to real-world problems. Each chapter discusses a set of statistical procedures, grouped as they are in the StatTools menu structure. Example models are also included.
Compatibility: StatTools is compatible with Excel versions 2000 through 2007.
