A New Statistics and Forecasting Toolset for your Spreadsheet
Have you ever needed forecasting, regression, quality control charts, or other statistical analyses beyond the basics that are provided with Excel? Have you ever doubted the accuracy of some of Excel's statistical results? StatTools addresses both of these issues, providing a new, powerful statistics toolset to Excel.
StatTools covers the most commonly used statistical procedures, and offers unprecedented capabilities for adding new, custom analyses. 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. Over 30 wide-ranging statistical procedures plus 9 built-in data utilities include forecasts, time series, descriptive statistics, normality tests, group comparisons, correlation, regression analysis, quality control, nonparametric tests, and more.
How StatTools Works
First, you define your data in StatTools. Then, you perform any of over 30 different types of analysis on your data set, depending on your situation.
StatTools provides a comprehensive and intuitive data set and variable manager right in Excel. You can define any number of data sets, each with the variables you want to analyze, directly from your data in Excel. StatTools intelligently assesses your blocks of data, suggesting variable names and locations for you. Your data sets and variables can reside in different workbooks, allowing you to organize your data as you see fit. Run statistical analyses that refer to your variables, instead of re-selecting your data over and over again in Excel. StatTools fully supports the expanded worksheet size in Excel 2007-2010. Plus, you can define variables that span multiple worksheets.
Once your data sets have been defined, choose a procedure from the StatTools menu or write your own, custom procedure. To write your own, 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, which allows you to utilize StatTools's built-in data management, charting and reporting tools.
