# Wizard Pro Changelog

## New in version 1.5.6

November 25th, 2014- Support DATETIME columns when importing SQLite files
- The .db extension is now recognized as SQLite
- Fix a few minor interface bugs
- Fix a few obscure crashes

### New in version 1.5.5 (November 12th, 2014)

- Fix several crashes:
- Viewing confidence intervals of the mean under 10.7 and 10.8 caused a crash
- Non-ASCII text in SPSS files sometimes caused a crash
- Creating a custom covariate partition in the Summary view caused a crash
- Very long text values sometimes caused a crash
- Proportional Hazards models with a specified cause of failure caused a crash
- New features for Contingency Table Analysis:
- McNemar Test (2 repeated binary measures)
- Cochran's Q (3 or more repeated binary measures)
- Stuart-Maxwell Test (2 repeated category measures)
- "Show Estimation Command" now works in the Summary view, too. (Generates commands for SPSS, SAS, Stata, and R)
- Pivot tables have improved support for hierarchical data
- Column > Subtract now works on date columns
- Summary view supports cross-column comparisons of category and survival-time data
- Proportional Hazards models are much faster

### New in version 1.5.4 (November 6th, 2014)

- Survival curves: dotted lines for censored values, and more grid lines for large graphs
- Accept percentage values in CSV files
- Support for importing DBF (dBase) files

### New in version 1.5.3 (October 31st, 2014)

- Support for Numbers 3.5 documents
- New repeated-measures tests: Wilcoxon signed-rank test for 2 numeric columns, Friedman test for 3 or more numeric columns
- Improved support for SAS7BDAT files created with Stat/Transfer
- Many speed improvements throughout the program
- Fix a freeze when customizing filters
- Some date/time values in CSV files were ignored
- Preserve date/time semantics when creating a new table from a Pivot table
- Fixed-effect models exported as XLS didn't work properly

### New in version 1.5.2 (October 17th, 2014)

- A new "Treat as Survival Times" option, which lets you produce survival (Nelson-Aalen) curves, view confidence bands, and perform log-rank tests. Survival analysis is perfect for analyzing failure, relapse, and mortality data, as well as other kinds of event data.
- Paired t-tests and repeated measures ANOVA: To analyze "before and after" data, just selecting multiple columns in the Summary view and checking the box labeled "Repeated Measures"
- Text partitions: Now you can group non-category text data into groups, e.g. A-G, H-M, and N-Z.
- Export image data: The data behind all the graphics in the Summary view can now be exported as CSV or XLS.
- Zoom to filtered values: There's a new magnifying glass button in the top-right corner of the Data Filters pane that lets you zoom all the graphics to the filtered values.
- Improved prediction intervals: The Predict view will now draw prediction intervals in the response curve, in addition to displaying the numeric values.
- Interaction terms: Models can now include separate interaction terms between two explanatory variables. For continuous variables, this is the product of the two terms; for category variables, this is an extra set of dummy variables representing all possible combinations of the two terms. Interaction terms will "just work" in the Predict view and in export XLS models.
- Reorder outcome categories: If your outcome categories aren't ordered properly, now you can just drag and drop to rearrange them. This should make Ordered Probit models more immediately useful without having to create ad-hoc columns.

### New in version 1.5.1 (October 9th, 2014)

- Keep popovers open as you switch windows.
- New option to hide charts in the Summary view (View > Hide Summary Charts)
- Improvements to the SAS command importer
- Fix a crash when using a date/time column as a covariate
- Fix a crash when importing values of infinity or negative infinity

### New in version 1.5.0 (October 1st, 2014)

- A new "Treat as Survival Times" option, which lets you produce survival (Nelson-Aalen) curves, view confidence bands, and perform log-rank tests. Survival analysis is perfect for analyzing failure, relapse, and mortality data, as well as other kinds of event data.

### New in version 1.4.14 (September 1st, 2014)

- Fix incorrect sorting of non-ASCII text
- Fix a bug in the display of confidence intervals for odds ratios in models
