Statistics Toolbox Release Notes

Updated Functions for ANOVA-Type Tables

Several functions display tables, such as ANOVA tables, in a figure window. These figure windows now have a new Copy Text option on the Edit menu. You can use this option to copy the table as tab-delimited text into Microsoft Excel, Microsoft Word, or other applications. These two functions that produce such tables have been updated:

• anova1
• anova2

The changes to each of these functions are described below.

Note    The aoctool, friedman, and kruskalwallis functions are new functions added in the Statistics Toolbox 3.0; these functions also display ANOVA-type tables.

anova1

• [p,table,stats] = anova1(x,group,'displayopt')
  

• New output table is a cell array of the ANOVA table values, including row and column labels.
• Now returns a stats output structure useful for performing multiple comparisons (see multcompare for more information).
• New input 'displayopt' is 'off' to omit the table and boxplot display, or 'on' (the default) to display the table and boxplot.
• If x is a matrix, group can now be a character array or cell array of strings with one row for each column of x. The boxes in the boxplot are then labeled using the rows of group.
• If x is a vector, group can be a vector of integers or a character array or cell array of strings with one row for each element of x. The boxes in the boxplot are labeled with values from group.
• P-value added to both table and to the table display.
• Now accepts group numbers that are not of the form 1, ..., g.

anova2

• [p,table,stats] = anova2(x,reps,'displayopt')
  

• Now returns table as a second output.
• The additional input 'displayopt' can be used to suppress the ANOVA table display.
• The additional output stats can be used as input to multcompare to perform multiple comparisons of row or column means.
