Prism 8.0.0 was released on October 15, 2018.
Introducing all-new graphs, data tables and analyses.
Highlights
- Mixed effects model for analysis of repeated measures ANOVA with missing data
- Multiple Variables Data Table for Multiple Linear Regression Analysis
- Nested Data Table for Nested t test and Nested One-way ANOVA (Mixed Effects Model)
- Violin Plots for data distribution visualization.
- Grouped graphs that show both bars and individual points.
- Draw lines or brackets with centered text. Ideal for placing significance asterisks.
- More normality tests and plotting.
- More comprehensive options for one-, two- and three-way ANOVA.
- Graph customization and annotation options
- And much more!

Graphing
- Better data distribution visualization
- Create Violin Plots for data distribution visualization
- Scatter plots showing data distribution without “smiles”
- Choose to display both individual data points as well as a bar and error bar for grouped graphs
- Generate Smoothing Splines and Akima Splines for your scatter plot data
- Annotations for bar graphs
- Label bar graphs with mean, median, or sample size on top or within the bars
- Place bar labels within - rather than under - bars of bar graphs
- Draw lines and brackets with centered text - indicate statistical significance with asterisks
- Adjust the color of any block of values, such as sub-columns in Grouped data tables, or rows in Column data tables
- Improved options for coloring and labeling Heat Maps

Analysis
- Perform Multiple Linear Regression with the NEW Multiple Variables data table
- Perform Poisson regression for count data
- Indicate which main effects and interactions to include along with transformations of parameters in the model
- Compare two alternative models and compare goodness of fits
- Test for residual normality and parameter multicollinearity
- Extract and rearrange data from Multiple Variables data table to other data table types
- Perform “Repeated Measures ANOVA with Missing Data” using Mixed Effects Model (automatically)
- Other major ANOVA improvements
- Analyze Three-way ANOVA in any or all of the three factors
- Correct for lack of sphericity using Geisser-Greenhouse correction
- Test for homogeneity of variance using Spearman’s rank correlation test for heteroscedasticity
- Perform One-way ANOVA without assuming data sampled from populations with equal standard deviations (Brown-Forsythe and Welch ANOVA)
- Perform “Nested t tests” and “Nested One-way ANOVA” using the NEW Nested data table
- Avoid pseudoreplication by accounting for actual (or “biological”) and technical replicates
- Test column data for Normality and Lognormality and test whether data more likely came from Normal (Gaussian) or lognormal distribution
- Automatically create Volcano Plot after performing Multiple t test Analysis

Performance Improvements
- New Windows 64-bit version for handling larger data sets and faster computation
- Import and export larger Excel, TXT and XML files
- Better support for high DPI monitors and DPI-switching awareness when dragging application windows across high-DPI and non-high-DPI screens
- Increased performance of plotting graphs with a huge number of bar labels set to row numbers
- Non-linear regression is 1.5x faster than in Prism 7
- Exact nonparametric tests (Mann-Whitney, Kruskall-Wallis, Spearman correlation, Binomial test, etc), are 2x faster in than in Prism 7
- ROC curve analysis on huge samples is up to 10x faster than in Prism 7
- (Windows) Increased performance on switching between date and time tables and linked sheets, as well as opening Prism files containing such tables (dates and times)
- (Windows) Increased overall performance of saving and opening PZFX files
- (Windows) Increased the performance of creating series - especially for large data series
- (Mac) Increased performance on switching to data tables by dynamically adjusting column width when there are many rows
Bug Fixes
Over 50 bug fixes, including:
- Fixed missing CI for transforms defined as X[1] if asymmetric confidence intervals were chosen
- Fixed the issue when Prism got confused by rows it needs to skip while doing curve comparison in survival analysis
- Fixed the issue when no multiple comparison values were present in results if interrupt calculating exact P value using Kruskal-Wallis method in one-way ANOVA analysis
- Made it possible to move multiple selected sheets in the gallery mode at once
- Fixed the issue when heat maps could not be created from tables with many rows
- Fixed the issue when connecting lines were shown behind the error envelope on graphs, but should have been above
- (Windows) Fixed the issue where the height of the legend key was defined by the size of only the very first symbol directly after the key
- (Windows) Fixed the strange black wedge that unexpectedly appeared in the EPS file exported from Prism
- (Windows) Fixed the issue when the curve color did not match symbol color if some data sets were removed from the graph
- (Windows) Fixed the issue that the hooked coordinates for the grid lines did not automatically hook to the new duplicated analysis when cloning the graph
- (Windows) Fixed crash on duplicating family
- (Windows) Fixed crash after you delete data tables and linked sheets and undoing the delete command
- (Windows) Fixed the issue when individual formatting of data points was lost on a grouped graph with points after duplicating family and applying some changes in a range of Y axis
- (Windows) Improved usability of vertical scrolling in data tables, so that, it is not so fast and can be interrupted
- (Mac) Fixed the issue when alignment of graphs was lost on layout sheet after re-opening Prism Win project in Prism Mac version
- (Mac) Fixed the issue when the labels of additional ticks, starting with the thirty-first tick, get clustered in the upper left corner of the screen
- (Mac) Fixed the issue when 'Align Middle' and 'Align Center' options worked incorrectly for selected drawing objects
