On October 1, a number of new features were added to the Real Statistics Resource Pack. I inadvertently forgot to publicize these new capabilities at the time, and so I am doing this now. All these features are included in the latest release and are available for **free download** by clicking on the **Download** tab of the home menu on the website.

The following is a description of these features:

**Factor Analysis: **A new **Factor Analysis** data analysis tool has been added. You can access this and all the other data analysis tools by pressing **Ctrl-m**. Supported features include

- Principal Component and Principal Axis extraction
- Descriptive statistics, correlation matrix, partial correlation matrix
- Eigenvalues and eigenvectors of the correlation matrix
- Scree plots
- KMO
- Communalities and specific variance
- Factor loading matrix (full and reduced)
- Factor matrix (both unrotated and rotated using Varimax)
- Reproduced correlation matrix
- Error matrix
- Factor score matrices (regression, Bartlett’s and Anderson-Rubin)

**Non-parametric tests: **Both one-tail and two-tests are now performed when the **Non-parametric option** is chosen on the **T Tests and Non-parametric Equivalents** data analysis tool.

**DFFITS: **This statistic is now outputted from the Linear Regression data analysis tool using the **Residuals and Cook’s Distance** option.

Also you may have noticed that there are now two files with examples from the website which can be downloaded for free by clicking on the** Download** tab of the top menu of the website:

- The new
**Real Statistics Multivariate Examples**file contains all the multivariate statistics examples (Hotelling’s tests, MANOVA, Factor Analysis, etc.) - The
**Real Statistics Examples Workbook**, which contains all the non-multivariate examples found on this website

Sorry for the delay in informing you of these new capabilities. I hope that you find them useful and that you continue to derive value from the *Real Statistics Using Excel* site and software.
