Admittedly, Microsoft has recently revised many of Excel s statistical functions to make them more accurate numerically and to provide a more consistent naming convention, but the functionality and user interface of Analysis ToolPak have changed hardly at all.
Indeed, its current form is almost identical to its form then. Since the early days of Excel at least 20 years ago Analysis ToolPak has been part of Excel.
