This dataset was generated to test two specific computational aspects of ANOVA
software. The generated data is based on work published by Stephen Simon and
James Lesage. They identified two types of error that can particularly affect
ANOVA computations, cancellation error and
accumulation error. Software that is not written
to control these errors can produce inaccurate output which can sometimes be
serious enough to change the qualitative conclusions of the data analysis.
Even though the primary focus of these datasets is identification of problems caused by cancellation or accumulation error, these datasets may also identify errors in other aspects of ANOVA software such as computation of degrees of freedom or errors in the ANOVA table from other sources.
The formula used to generate this data is:
