This function defines which statistics are printed in the final table and how they are formated.
The format depends on the class x
. See section methods.
If you are not pleased with the current format you may alter these functions.
But you must keep the original output-format, see section Value.
Function check_format_statistics
checks if the output of statistics is suitable for further processing.
