Mosaic and Parquet Diagrams

Aabel provides both simple graphs and matrices of mosaic and parquet diagrams, along with easy to use tools for customizing the diagrams.

The mosaic plot is a graphical method for visualizing n x m contingency tables. The areas of the mosaic tiles are proportional to the observed frequency of groups in the contingency table.

In a parquet plot, the area of each tile is proportional to the expected frequency of groups in the contingency table.

In Aabel, the diagram tiles can be color coded using:

Pearson's goodness-of-fit chi-square
Likelihood ratio chi-square
Freeman-Tukey residuals
Linear residuals (normalized)
Observed frequency
Expected frequency

For identifying categories with missing data, you can color rows or columns of tiles by category.

The data used to plot the matrix diagram below is from the report on the loss of the Titanic (S.S.), British Board of Trade Inquiry (1990).
