With the XLMiner Analysis ToolPak Add-on, you can easily perform statistical analyses of the same types available in the Analysis ToolPak add-in that has been part of Microsoft Excel for over 20 years, and has been featured in large numbers of textbooks, videos, statistics courses and the like. The add-on provides all 19 interactive functions included in the Excel Analysis ToolPak, plus a 20th function often requested by users, logistic regression. Sidebar input fields and output on the spreadsheet will be very familiar to Excel Analysis ToolPak users. The 20 functions are: ANOVA: Single Factor ANOVA: Two-Factor with Replication ANOVA: Two-Factor without Replication Correlation Covariance Descriptive Statistics Exponential Smoothing F-Test Two-Sample for Variances Fourier Analysis Histogram Linear Regression Logistic Regression Moving Average Random Number Generation Rank and Percentile Sampling t-Test: Paired Two-Sample for Means t-Test: Two-Sample Assuming Equal Variances t-Test: Two-Sample Assuming Unequal Variances z-Test: Paired Two-Sample for Means Results will generally match the Excel Analysis ToolPak, as seen in many textbooks, screen images and videos. The add-on's Random Number Generation function uses the Mersenne Twister algorithm.
